Gaza is a Palestinian city in the Gaza Strip, with a population of about 450,000, making it the largest city in the Palestinian territories. Inhabited since at least the 15th century BCE, Gaza has been dominated by several different peoples and empires throughout its history. The Philistines made it a part of their pentapolis after the Ancient Egyptians had ruled it for nearly 350 years. In 635 CE, it became the first city in Palestine to be conquered by the Rashidun army and quickly developed into a centre of Islamic law. As a result of the 1948 Arab–Israeli War, Egypt administered the newly formed Gaza Strip territory and several improvements were undertaken in the city. Gaza was captured by Israel in the Six-Day War in 1967, but in 1993, the city was transferred to the Palestinian National Authority. Following the 2006 election, conflict broke out as the Fatah party seemed unwilling to transfer power to Hamas, resulting in Hamas taking power in Gaza by force. Most of Gaza's inhabitants are Muslim, although there exists a Christian minority.
