Borders of Israel in the context of "Demarcation line"

Israel, officially the State of Israel, is a country in the Southern Levant region of West Asia. It borders Lebanon to the north, Syria to the northeast, Jordan to the east and Egypt to the southwest. Israel occupies the Palestinian territories of the West Bank in the east and the Gaza Strip in the southwest, as well as the Syrian Golan Heights in the northeast. Israel's western coast lies on the Mediterranean Sea, the southern tip reaches the Red Sea, and the east includes the Earth's lowest point near the Dead Sea. Jerusalem is the government seat and proclaimed capital, while Tel Aviv is Israel's largest urban area and economic centre.

The Land of Israel is synonymous with Palestine or the Holy Land. In antiquity it was home to the Canaanites and later the kingdoms of Israel and Judah. Its location at a continental crossroads brought demographic shifts under various empires. Nineteenth-century European antisemitism fuelled the Zionist movement for a Jewish homeland. Britain endorsed this goal in the 1917 Balfour Declaration and ruled Mandatory Palestine from 1920. Jewish immigration and British policies intensified Arab-Jewish tensions, and the 1947 United Nations (UN) Partition Plan led to a civil war.

The Egypt–Israel barrier or Egypt–Israel border fence (Hebrew: שְׁעוֹן הַחוֹל, romanized: Sheʽon HaḤol, lit. 'sand clock') refers to a separation barrier built by Israel along its border with Egypt. Initial construction on the barrier began on 22 November 2010, and its original purpose as a common fence was to curb the large influx of illegal migrants from African countries into Israel. However, in the wake of the Egyptian Crisis after the 2011 Revolution, Israel's southwestern border with Egypt experienced an increase in militant jihadist activity with the outbreak of the Sinai insurgency. In response, Israel upgraded the steel barrier—called Project Hourglass by the Israel Defense Forces (IDF)—to include cameras, radars, and motion detectors. In January 2013, construction on the barrier's main section was completed; the final section was completed in December 2013.

A number of countries, including the United States and India, have sent delegations to Israel to observe its border-controlling capabilities and the various technologies used by the IDF to secure Israel's boundaries against the Arab states. Some of these countries have expressed an interest in implementing Israeli strategies and technologies with their own border fences; the Trump administration cited Israel's border strategies as inspiration for the barrier built by the United States along its border with Mexico, while Indian officials have discussed the implementation of an "Israel-type model" for the barrier built by India along its border with Pakistan.

The Six-Day War, also known as the June war, 1967 Arab–Israeli war or third Arab–Israeli war, was fought between Israel and a coalition of Arab states, primarily Egypt, Syria, and Jordan from 5 to 10 June 1967.

Military hostilities broke out amid poor relations between Israel and its Arab neighbors, who had been observing the 1949 Armistice Agreements signed at the end of the First Arab–Israeli War. In 1956, regional tensions over the Straits of Tiran (giving access to Eilat, a port on the southeast tip of Israel) escalated in what became known as the Suez Crisis, when Israel invaded Egypt over the Egyptian closure of maritime passageways to Israeli shipping, ultimately resulting in the re-opening of the Straits of Tiran to Israel as well as the deployment of the United Nations Emergency Force (UNEF) along the Egypt–Israel border.

African immigration to Israel is the international movement to Israel from Africa of people who are not natives or do not possess Israeli citizenship in order to settle or reside there. This phenomenon began in the second half of the 2000s, when a large number of people from Africa entered Israel, mainly through the then-lightly fenced border between Israel and Egypt in the Sinai Peninsula. According to the data of the Israeli Interior Ministry, 26,635 people arrived illegally in this way by July 2010, and over 55,000 by January 2012. In an attempt to curb the influx, Israel constructed the Egypt–Israel barrier. Since its completion in December 2013, the barrier has almost completely stopped the immigration of Africans into Israel across the Sinai border.

The African refugee population in Israel is composed primarily of Sudanese and Eritrean refugees migrating to Israel through the Sinai Desert. Israeli policy concerning these refugees has evolved from a policy of neutrality to a policy of deterrence. These refugees began arriving in Israel in the 21st century, led by Bedouin smugglers. As of 2018, the non-Jewish African refugee population in Israel is approximately 36,000.

The Battle of the Yarmuk (also spelled Yarmouk; Arabic: معركة اليرموك) was a major battle between the army of the Byzantine Empire and the Arab Muslim forces of the Rashidun Caliphate, and a crucial point in the Muslim conquest of the Levant. The battle consisted of a series of engagements that lasted for six days in August 636, near the Yarmouk River (called the Hieromykes River by the Greeks), along what are now the borders between Syria and Jordan and Syria and Israel, southeast of the Sea of Galilee. The result of the battle was a decisive Muslim victory that ended Roman rule in Syria after about seven centuries. The Battle of the Yarmuk is regarded as one of the most decisive battles in military history, and it marked the first great wave of early Muslim conquests after the death of the Islamic prophet Muhammad, heralding the rapid advance of Islam into the then-Christian/Roman Levant.

To check the Arab advance and to recover lost territory, Emperor Heraclius had sent a massive expedition to the Levant in May 636. As the Byzantine army approached, the Arabs tactically withdrew from Syria and regrouped all their forces at the Yarmuk plains close to the Arabian Peninsula, where they were reinforced, and defeated the numerically superior Byzantine army. The battle is widely regarded to be Khalid ibn al-Walid's greatest military victory and to have cemented his reputation as one of the greatest tacticians and cavalry commanders in history.

The Six-Day War, or the 1967 Arab–Israeli war (5–10 June 1967), was fought between Israel and a coalition of Arab states, primarily Egypt, Syria, and Jordan within the context of the Arab–Israeli conflict. In the war, Israel captured and occupied the West Bank (including East Jerusalem) from Jordan, the Gaza Strip and the Sinai Peninsula from Egypt, and the Golan Heights from Syria.
