What is the name of Hassan Khomeini's grandfather
Ruhollah Khomeini Sayyid Ruhollah Mūsavi Khomeini (Persian: سید روح‌الله موسوی خمینی‎ ‎ ] ; 24 September 1902 – 3 June 1989), known in the Western world as Ayatollah Khomeini, was an Iranian Shia Muslim religious leader, philosopher, revolutionary, and politician. He was the founder of the Islamic Republic of Iran and the leader of the 1979 Iranian Revolution that saw the overthrow of the 2500 years of Persian monarchy and Mohammad Reza Pahlavi, the last Shah of Iran. Following the revolution, Khomeini became the country's Supreme Leader, a position created in the constitution of the Islamic Republic as the highest-ranking political and religious authority of the nation, which he held until his death. He was succeeded by Ali Khamenei on 4 June 1989.
Foreign relations of Iran Foreign relations of Iran refers to inter-governmental relationships between the Islamic Republic of Iran and other countries. Geography is a very significant factor in informing Iran's foreign policy. Following the 1979 Iranian Revolution, the newly born Islamic Republic, under the leadership of Ayatollah Khomeini, dramatically reversed the pro-American foreign policy of the last Shah of Iran Mohammad Reza Pahlavi. Since then the country's policies have oscillated between the two opposing tendencies of revolutionary ardour, which would eliminate Western and non-Muslim influences while promoting the Islamic revolution abroad, and pragmatism, which would advance economic development and normalization of relations. Iran's bilateral dealings are accordingly sometimes confused and contradictory.
