The main IGO that took part in the Yemen conflict was the Arab League. During Yemen's civil war between 1962 and 1970, the Arab League consisted of six member states that included Yemen, Syria, Saudi Arabia, Lebanon, and Jordan. However, the Arab League was later expanded to include twenty-two member states. The role played by the Arab League during the civil war in Yemen is evident from the role played by individual members of this union to promote its interests. Egypt was known as the United Arab Republic during this conflict and had good relations with Yemen. In 1958, Yemen joined Egypt and Syria and the resulting union was known as the United Arab State. However, this union did not last long as it was soon dissolved in 1961 after Syria's secession from the union. In 1962, Mohammed Al-Bdr assumed leadership of Yemen after the death of Imam Ahmed. A week after Al-Bdr came to power, revolutionary forces, led by soldiers, overthrew the new leader and declared Yemen to be an Arab republic (Caton 21). Mohammed Al-Bdr and other members of the royal family fled to the northern part of Syria where they joined forces with some tribes living in that region. The newly formed royal union received material and financial support from outside and used these resources to wage war on the republicans in the capital. The republican forces that had overthrown the Imam's leadership accused Saudi Arabia of supporting Al-Bdr forces and threatened to bring war to its territory. Mohammed Al-Bdr and the royal forces, on the other hand, accused Egypt of initiating and supporting the army's rebellion in Yemen, but Egypt vehemently denied such claims.
