The territories of Gaza Strip and West Bank, collectively known as Palestine, are a disputed territory between Israel and the government of the Palestinian Territories, naming the country the State of Palestine. It's Palestinian National Authority a UN observer member, granted such status in 2012 despite Israeli protests. The Palestinians claim as well East Jerusalem while some claim all of Israel as well. The origins of the modern concept of a Palestinian state originate in the 1947 UN partition plan dividing British Palestine between Israel and a theoretical Arab state. However, many of the Arab leaders opposed giving Israel such a state in Palestine, and when Israel declared independence in 1948, the Arab countries, fearing that the Israelis might occupy the whole former British Palestine, declared war on Israel in the first Arab-Israeli Conflict. The Palestinian Arabs fought with militia groups alongside the Egyptians, Jordanians, Syrians, and Lebanese. When a ceasefire was imposed, the Egyptians occupied what is now the Gaza Strip and Jordan annexed what is now the West Bank. Jerusalem is divided into two, the Israeli West and the Jordanian East, including the Temple Mount. When the Six Day War occured in 1967, the Israelis captured East Jerusalem, West Bank, and the Gaza Strip. Needless to say, many of the Palestinian Arabs are not amused. Some groups, one of the them the Fatah group led by Yassir Arafat, fought a campaign against Israel, using guerrilla tactics, but also using terrorist warfare like hijacking and bombing Israeli places. In the late 1970s and 80s, Menachem Begin formally included the Palestinian territories to Israel and they are considered as such on Israeli maps at that time. Jordan formally surrendered its claim on the West Bank after Egypt had all but renounced it earlier at the Camp David talks. The Infitada of 1987 erupted against Israeli control, though it was marred by violence from left to right. In 1994, the Oslo peace accords between Arafat, now the leader of the Palestinian National Authority, and Israeli PM Rabin had set a timetable on a future Palestinian state. However, there are many issues that remained to be solved like the Israeli settlements, the remaining Palestinian refugees, East Jerusalem, etc. that are unresolved to this day, and this caused a second Infitada in 2000. In 2005, Israel unilaterally withdrew from the Gaza Strip due to many Israeli soldiers being killed there. The West Bank is mainly controlled by the Fatah Party led by Mahmoud Abbas.
The Palestinian flag
The flag is based on that of the Arab Revolt against the Ottomans back in World War I (save for the white and green reversed).
