Muhammad al-Badr (15 February 1926 – 6 August 1996) was the last king and Zaydi Imam of the Mutawakkilite Kingdom of Yemen (North Yemen) and leader of the monarchist regions during the North Yemen Civil War (1962–1970).

He was Imam and Commander of the Faithful and King of the Mutawakkilite Kingdom of Yemen.

Early life Al-Badr was born in 1926 in the town of Hajjah in north-west Yemen, as oldest son of Ahmad bin Yahya, later imam of the Zaydis and king of North Yemen. His father was governor of Hajjah. Al-Badr was named as deputy over Hodeidah. He took the name Sayf al-Islam al-Badr.

In 1955 Ahmad bin Yahya forged connections and signed agreements during a tour to Soviet bloc countries. In April 1956 he signed a mutual defence pact with Egypt, involving a unified military command, and in 1958 incorporated Yemen with the United Arab Republic of Egypt and Syria into what then became the United Arab States.

On 8 March 1958, Nasser and Prince Muhammad al-Badr signed a pact in Syria creating the United Arab States, a federation linking Yemen with the United Arab Republic (Egypt and Syria). Yemen retained its independence and the ability to act against Egypt in foreign policy. Field Marshal Abdul Hakim Amer was appointed commander-in-chief of the federation's joint forces.

Foreign relations Relations with the Soviet Union According to historical accounts, Soviet economic delegations established a working relationship with Crown Prince al-Badr during a period when the Free Yemeni Movement was actively opposing Imam Ahmad's rule. Al-Badr sought to modernize Yemen and was prepared to cooperate with any nation offering developmental assistance. He publicly identified with Nasser's Arab nationalist ideology and responded positively to Soviet economic overtures.

Several of al-Badr's relatives held unfavorable views of him. His cousin, Abdullah ibn al-Hussein, reportedly characterized al-Badr as "dissolute, incompetent, and gullible." A Soviet physician working in Yemen in 1961 later wrote about a parade in Sana'a where al-Badr was honored by mounted soldiers and tanks, while surrounded by bodyguards dressed in blue.

During the 1950s, Soviet strategy in Yemen was characterized by small-scale, long-term planning with minimal risk. In 1955, the USSR concluded a Treaty of Friendship with Yemen. Imam Ahmad received sufficient light weaponry to conduct attacks against British forces, but not enough to initiate a major conflict that would require direct Soviet involvement. Moscow's calculation was that continued dependence on Soviet weapons would make Yemen reliant on Soviet technicians, spare parts, and future shipments. Soviet officials encouraged Ahmad to attack British positions — an action he would likely have taken regardless. A decisive British victory appeared improbable, and periodic Yemeni attacks had the potential to erode Britain's regional position.

Moscow viewed Yemen as a potential staging ground for Soviet expansion into the Arabian Peninsula at the expense of Western interests. Vladimir Sakharov, a Soviet diplomat assigned to the Yemen Arab Republic who later defected to the United States in 1971, explained that the USSR maintained no diplomatic relations with Saudi Arabia or the Gulf sheikhdoms at that time. He stated that North Yemen and South Arabia were seen as a Soviet entry point into both the Arabian Peninsula and the Red Sea.

A bilateral trade agreement signed in 1956 between Yemen and the Soviet Union initiated several infrastructure projects, including factories for cement, leather processing, juice production, and metal packaging, as well as an oil storage depot and a new port facility at Hodeidah. Soviet trade delegations monitored the implementation of these projects in January and March 1956. A credit line of $3.5 million was extended to Yemen. In July 1956, al-Badr led a well-publicized Yemeni delegation of twelve ministers to Moscow to formalize military and economic cooperation — the first visit of any Arab leader to the USSR. During the same trip, al-Badr also visited East Berlin from 25 June to 2 July 1956 as a guest of the East German government. Al-Badr obtained his father's permission to tour China, the Soviet Union, and other Eastern European countries only after demonstrating his reliability by rallying tribal allies following the failed 1955 coup attempt.

The first Soviet diplomatic mission opened in Ta'izz in January 1958. The Soviet ambassador to the United Arab Republic was concurrently asked to serve as chargé d'affaires for Yemen, which led to a second Yemeni delegation traveling to Moscow in 1959.RGANI, Fond 5, Opis 30, Dela 452, List 30–38, June 1964.

Following that visit, China dispatched engineers and laborers to construct roads in Yemen, while the Soviet Union sent specialists to begin work on the port at Hodeidah.GARF, Fond 4459, Opis 24, Dela 2125, File 5, November 1, 1959. TASS-Peking.

In 1957, only fifty Soviet and Chinese specialists were present in Yemen. By 1959, the number had grown to six hundred Chinese and several hundred Russians. By 1960, more than 1,100 Chinese laborers were employed on Yemeni road projects. The new Hodeidah facility, named Port Ahmad, required 300,000 tons of modern construction materials and was designed to store 9,000 tons of oil. The surrounding area was to be equipped with electricity, mechanized factories, vehicles, and Soviet technicians. Yemen received an additional $2 million credit for these projects.RGANI, Fond 5, Opis 30, Dela 452, List 30–38, June 1964. Brief Yemeni history written by V. Kornev.

Soviet press reports covered the arrival of tractors, excavators, and other heavy machinery at the port site, stating that Soviet-Yemeni friendship and fraternal cooperation had grown. According to Soviet media, the two countries had together achieved "a new brightness" in completing Port Ahmad as "a port of peace and friendship."AVPRF, Fond 585, Opis 5, Papka 4, Dela 6, January 1962. Notes from the Soviet Mission to Yemen.

Moscow supported Ahmad despite describing his country as "feudal" and his rule as an absolute theocracy. Soviet officials considered his palace "modest" and acknowledged his efforts to improve public health. However, according to academic sources, the primary target of Soviet foreign policy was al-Badr, who preferred rapid modernization with Soviet assistance.

In the spring of 1962, al-Badr organized another trade delegation to Moscow to accept a Soviet proposal to use Yemen as a transit point for oil shipments to Africa. His pro-Soviet orientation was clearly expressed in a speech he delivered in June 1962 at the opening ceremony of Port Ahmad in Hodeidah, less than four months before the revolution. He began with poetic verses celebrating the Yemeni people's achievement in building the port. He then praised the Soviet Union for its assistance, stating: "We and the Soviet People — Brothers, you are the most true and faithful of our friends … Many thanks to the Soviet government for their generous help to Yemen."GARF, Fond 4459, Opis 24, Dela 2555, File 24–25, April 7, 1961.

Later in the same speech, he added: "Port Ahmad is the first of projects that are needed to carry out the service for the benefit of our own country … thank our dear friends."AVPRF, Fond 585, Opis 5, Papka 4, Dela 62, June 14, 1962. Report of the Soviet Mission to Yemen.

In his Port Ahmad address, al-Badr characterized the facility as merely the first of many future Yemeni-Soviet projects, indicating his desire for a long-term relationship between the two countries. In a eulogy for his father delivered on 21 September 1962, al-Badr claimed that Ahmad's dying wish was to "adopt socialist economic, military, and political standards for the people."AVPRF, Fond 585, Opis 14, Papka 7, Dela 10, File 1, September 21, 1962. "The New Imam's Reforms." Soviet First Secretary Nikita Khrushchev echoed this sentiment, describing Ahmad as having "made a worthy contribution to the cause of consolidating the political and economic independence of Yemen."

Armin H. Meyer, a former American ambassador to Iran, referred to al-Badr as the "red prince." According to Meyer, al-Badr had grown impatient with the West, traveled to Moscow where he was entertained, and proceeded to procure arms from the Soviets. Months later, when al-Badr was overthrown by recipients of those same weapons, the Soviets quickly recognized his successors without public regret.Department of State, Central Files, DEF 19-8 US-Iran, Telegram From the Embassy in Iran to the Department of State, July 11, 1966. David Holden, the Middle East correspondent for The Guardian, described al-Badr as "woolly-minded" — sincerely anxious to reform his country but lacking a clear understanding of how to do so or what passions such reforms might unleash. Holden concluded that al-Badr's good intentions ultimately paved the way to his downfall.

Relations with Gamal Nasser According to al-Badr's own later account, Nasser recruited him for a plot to overthrow his father and secure an Egyptian presence on the Arabian Peninsula. During a lengthy conversation with British MP Neil McLean in the civil war, al-Badr admitted that his naivety and overconfidence had nearly led him to sacrifice his father and Yemeni independence for what he called empty promises. According to the same account, Nasser had cultivated al-Badr as a protégé during his repeated trips to Cairo, hoping to gain a Nasserist ally in South Arabia.

Some scholars suggest that al-Badr may have exaggerated certain details to justify his earlier pro-Egyptian and pro-Soviet stances. The fact that he told these stories at length to McLean — who passed them to the British mercenary network in Yemen — indicates a possible desire to explain his past actions. Nevertheless, his account matches his known travel itinerary and provides context for meetings that otherwise lack official documentation.

Regardless of the exact accuracy of every word, the confession reveals al-Badr's mindset and that of his British supporters. Al-Badr portrayed himself as an unwitting victim of Nasser's plotting. The British, for their part, attempted to convince critics that their imperfect ally had genuinely turned away from his earlier anti-British and pro-Nasser policies and was now worthy of their backing.

Al-Badr and Nasser first met in 1954 during a two-month visit to Cairo. Following that meeting, Nasser announced a large aid programme for Yemen. During another trip to Cairo in 1955, al-Badr met with the local branch of the Yemeni Union and cultivated a group of supporters within the Free Yemeni Movement. On his third visit to Cairo in 1956 to sign the Jeddah Defence Pact with Egypt, al-Badr promoted thirteen Yemeni cadets from an Egyptian military school to the rank of first lieutenant. Several months later, after graduation, the cadets arrived in Yemen and were personally greeted by al-Badr at Hodeidah port.

One of the thirteen, Abd al-Latif Dayfallah — a future Yemeni prime minister — later recalled: "The thirteen Yemeni officers — by the way the same number as the Egyptian Free Officers — was quickly being molded into the Egyptian model. The Egyptian Free Officers movement which overthrew the monarchy in Egypt was something we emulated." Dayfallah and Abdullah Juzaylan (also among the thirteen) were instrumental in forming the Yemeni Free Officer movement in 1960. This group of young officers later became the core of the September 1962 overthrow of the imam.
