Mujahideen (Arabic: مجاهد‎ muǧāhid, nominative plural مجاهدون muǧāhidūn, oblique plural مجاهدين muǧāhidīn "strugglers" or "people doing jihad") are Muslims who believe they struggle in the path of God. The word is from the same Arabic triliteral root as jihad ("struggle").

Mujahideen is also transliterated from Arabic as mujahedin, mujahedeen, mudžahedin, mudžahidin, mujahidīn, mujaheddīn and more.

The beginnings of Jihad are traced back to the words and actions of Muhammad and the Qur'an. The people who helped Muhammad during the early periods of his prophethood were referred to as Ansars ("helpers") and Muhajirs ("immigrants"),. Then the Muhajireen's property was confiscated in Makkah, so the Prophet called upon the Muslims to participate in Jihad against Quraysh.

The earliest known expeditions they participated in were the Caravan raids, where they were given the task of intercepting Quraysh caravans. They also participated in other battles, such as the Battle of Badr and Uhud.

The modern phenomenon of jihadism, i.e., the movement within radical Islamism that presents jihad (offensive or defensive) as the casus belli for insurgencies, guerilla warfare and international terrorism, dates back to the 1960s and draws on early-to-mid-20th century Islamist doctrines such as Qutbism.

Ronald Wilson Reagan ( /ˈrɒnəld ˈwɪlsən ˈreɪɡən/; February 6, 1911 – June 5, 2004) was the 40th President of the United States, serving from 1981 to 1989. Prior to that, he was the 33rd Governor of California from 1967 to 1975 and a radio, film and television actor.

Born in Tampico, Illinois and raised in Dixon, Reagan was educated at Eureka College, earning a Bachelor of Arts degree in economics and sociology. After his graduation, Reagan moved first to Iowa to work as a radio broadcaster and then in to Los Angeles in 1937 where he began a career as an actor, first in films and later television. Some of his most notable films include Knute Rockne, All American, Kings Row, and Bedtime for Bonzo. Reagan served as president of the Screen Actors Guild, and later as a spokesman for General Electric (GE); his start in politics occurred during his work for GE. Originally a member of the Democratic Party, his positions began shifting rightward in the late 1950s, and he switched to the Republican Party in 1962. After delivering a rousing speech in support of Barry Goldwater's presidential candidacy in 1964, he was persuaded to seek the California governorship, winning two years later and again in 1970. He was defeated in his run for the Republican presidential nomination in 1968 as well as 1976, but won both the nomination and general election in 1980, defeating incumbent Jimmy Carter.
