Timeline: The long history of the Israeli-Palestinian conflict

The Hamas terrorist attack on Israel this weekend comes amid the backdrop of a longstanding history of conflict over land and independence that has plagued the region.

The early 1900s: British promote Zionist movement for a 'national home' for Jewish populations

The Balfour Declaration, issued by the British government in 1917, announced Britain's promise for a "national home for the Jewish people" in Palestine, which was then under the rule of the Ottoman Empire.

The promise appeased the Zionist movement, who believe in a Jewish right to the land of Jerusalem -- or Zion.

Following the end of World War I, the region of Palestine was conceded by the Ottoman Empire and was placed under the rule of the British via a mandate from the League of Nations.

The mandate was criticized for not taking into account the wants and needs of the Palestinians who resided in the land and wanted independence.

Britain's promise, as well as Nazi persecution and the Holocaust during World War II, is cited as what led tens of thousands of Jewish civilians to migrate to Palestinian land into the 20s and 30s.

Ongoing clashes between Palestinian Arabs and Jewish migrants in the region led to hundreds of deaths.

1947-48: Partitioning Palestine into two states, the Arab-Israeli War begins

In February 1947, the British proposed that the United Nations consider the future of Palestine and take over relations in the region amid ongoing tension.

The United Nations later adopted a resolution to split Palestine into two independent states -- a "Jewish State" and an "Arab State" with Jerusalem under UN trusteeship, despite opposition from Palestinian Arabs of the region.

Jerusalem, a city with religious significance to many groups, would remain under international control administered by the United Nations.

Palestinians refused to recognize the resolution, and violent conflict between both groups continued.

On May 15, 1948, Israel declared independence, thus beginning the Israeli-Arab War, with five Arab states fighting against the creation of the state.

Palestinians were forced off their lands or fled en masse, marking the first large-scale exodus in what would become a decades-long battle over land ownership, according to the United Nations.

Israel, backed by foreign powers, won the war, and the territory was divided into three parts -- Israel, the West Bank, and the Gaza Strip. Egypt and Jordan retained control of the West Bank and Gaza Strip respectively until 1967.

The Gaza Strip is a 140 square mile strip of land along the Mediterranean Sea surrounded by Israel and Egypt. It is currently home to roughly 2 million people.

The West Bank is a landlocked 2,200 square mile region bordered by Israel and Jordan with a population of roughly 3 million people.

1967: Six-Day War

On June 5, 1967, after a prolonged attrition war between Israel and Egypt, the six day war broke out between Israel and its Arab neighbors.

After six days of war, Israel captured Palestinian Arab territories of the West Bank, East Jerusalem, Gaza, and the Sinai Peninsula, as well as the Syrian territory of Golan Heights.

The Six-Day War forced a majority of Palestinians to once again become refugees and began a decades long Israeli occupation of Palestinian territories.

1987: First Palestinian 'intifada,' or uprising, occurs

The first yearslong uprising from Palestinian forces in their struggle for self determination began in 1987.

It ended in 1993, when Israel's then-Prime Minister of Israel Yitzhak Rabin, and then-leader of the Palestine Liberation Organization (PLO) Yasir Arafat signed the Oslo accords, which declared the PLO as a representative for the Palestinian people and recognized Israel's "right to exist in peace," according to the United States Department of State.

A second Intifada (2000) from Palestinian forces, which ended in 2005, led to the Palestinian people's autonomous control of the West Bank and Gaza.

In 2005, Israel disengaged from the Gaza Strip, uprooting its settlements in the region.

The following year, Hamas won an election to control the Gaza Strip, kicking out representatives of the PLO. The armed takeover of Gaza by Hamas in 2007 prompted Israel to impose a blockade on Gaza.

Israel imposes blockade

Following the armed takeover, the surrounding countries of Israel and Egypt imposed a blockade on the Gaza Strip which greatly restricts the movement of people and goods into and out of the area.

These restrictions have been a concern of humanitarian groups around the world about the conditions in which Palestinians are forced to live.

According to the European Commission, Palestinians are "denied adequate housing, access to services while subjected to forced evictions and movement restrictions."

"In Gaza, recurrent cycles of hostilities, greater divisions, and a blockade have considerably worsened people's living conditions," the European Civil Protection and Humanitarian Aid Operations states on its website.

According to the United Nations, 81% of the population in Gaza lives in poverty with food insecurity plaguing 63% of Gaza citizens. The poverty rate is 46.6%, and access to clean water and electricity remains inaccessible at "crisis" levels, the agency states.

In the years following, Hamas and Israel continue to engage in combat.

Roughly 6,400 Palestinians and 300 Israelis had been killed in the ongoing violence since 2008, not counting the recent fatalities, the UN reported.

Hamas launched thousands of missile attacks on Israel, and Israel fired massive strikes in retaliation.

Israel engaged in major, large-scale military operations including: the 22-day-long 2008 "Operation Cast Lead;" the 2012 "Pillar of Defense" eight-day operation; and the "Protective Edge" operation in 2014.

2023: The incursion against Israel by terrorist group Hamas

At least 1,200 people have died and 2,900 others have been injured in Israel after the terrorist militant group Hamas launched an incursion on Saturday, Israeli authorities said.Hamas fired thousands of rockets toward Israel and an estimated 1,000 fighters crossed into the country from the neighboring Gaza Strip. Israeli officials said at least 130 civilians and soldiers have been taken hostage.

Israeli forces have responded, declaring "a state of alert for war" and launching hundreds of retaliatory airstrikes on Gaza.

Palestinian authorities said at least 1,055 people have died and another 5,184 have been injured in Gaza by the Israeli response.

In the wake of the Hamas attack this weekend, Israeli defense officials said the flow of all food and power to Gaza was being cut off in preparation for a "total siege."

The attacks have launched renewed attention on the region's conflict, prompting protests around the world.
