I belongs to the Jews. The Bible says it over, and over, and over again.
True but the Bible is referring to spiritual not racial jews.
The Biblical Israelites were far more effective at ensuring that their possession was not disputed, than the modern Israelites
In the entire span of human habitation of the region going back many thousands of years the Jews have actually had sovereignty only a small percentage of the time:
200,0000 - 18,000 BC: The Mousterian Neanderthals were the earliest inhabitants of the area known to archaeologists, and have been dated to c. 200,000 BC.
18,000 - 10,500 BC: Kebarans - The first anatomically modern humans to live in the area were the (recent paleoanthropological evidence suggests that Kebarans may have arrived as early as 75,000 BC and shared the region with the Neanderthals for millennia before the latter died out).
10,500 BC - 8500 BC Epipalaeolithic Period (This and the other prehistoric cultures are named after archaeological sites, in the absence of any indication of what they called themselves.)
8500 BC - 4300 BC: Neolithic Period - Yarmukians People that began agriculture.
4300 BC - 3300 BC: Chalcolithic Period Ghassulians People became urbanized and lived in city-states, including Jericho.
3300 BC - 2300 BC: Early Canaanite Period - Abraham arrives from Ur (Iraq)
2300-1550 BC: Middle Canaanite Period - Jews abandon the Holyland and resettle in Egypt. Successive waves of migration brought other groups onto the region. Whether the migration to Egypt was a result of displacement by the new arrivals or the new arrivals filled a void left by the departure of the Jews is not known.
1550 BC - 1200 BC: Late Canaanite Period (Exodus)
1000 BC - 925 BC: Monarchy (Solomon) Period
925 BC - 722 BC: Divided Monarchies of Judah and Israel, Moab, Amon, and Philistia.
722 BC: The northern Kingdom of Israel was destroyed by the Assyrians, many of its inhabitants (mainly the elite amongst them) were deported (giving rise to the legend of "the Lost Tribes") and replaced by settlers from elsewhere in the Assyrian Empire.
586 BC - 539 BC: Neo-Babylonian Period - Destruction of the Temple in Jerusalem and beginning of Diaspora. The Babylonian Empire under Nebuchadnezzar conquered the (southern) Kingdom of Judah in 597 BC - 586 BC, and exiled the middle and upper classes of the Jews.
539-333 BC: Persian Period - Rebuilding of the Temple in Jerusalem. Cyrus II of Persia conquered the Babylonian Empire by 539 BCE and incorporated Judah and Israel into the Persian Empire. The Persians allowed Jews to return to the regions that the Bablyonians had exiled them from.
333 BC - 165 BC: Hellenistic Period - (Cultural legacy of the empire of Alexander the Great) In the early 330s BC, Alexander the Great conquered the region, beginning an important period of Hellenistic influence in Israel. After Alexander's death in 323 BC, his empire was partitioned, and the competing Ptolemaic and Seleucid Empires occupied various portions of the eastern Mediterranean, including different parts of Israel.
165 BC - 63 BC: Maccabean/Hasmonean Period Jews restore their sovereignty over Palestinian homeland The Jews were divided between the Hellenists who supported the adoption of Greek culture, and those who believed in keeping to the traditions of the past, which resulted in the Maccabean revolt of the 2nd century BC. Jews achieved sovereignty in Palestinian land throughout the Maccabean Period, and their Kingdom of Judea controlled most of the region of Israel.
63 BC - 70 AD Early Roman Period - The birth of Christ. Jewish insurrection against Roman occupation ultimately results in the collapse of Jewish sovereignty Following the Roman conquest in 63 BC, parts of Israel;first a client kingdom of the Roman Empire, after year 6 AD the Iudaea Province—were in nearly constant revolt against Roman occupation. The Great Jewish Revolt began in 66 AD and resulted in the destruction of Jewish temple in Jerusalem in 70 AD.
70 AD - 135 AD Late Roman Period - Destruction of the Temple in Jerusalem. The Great Jewish Revolt in 66 - 73 AD resulted in the destruction of the Jewish temple in Jerusalem and the sacking of the entire city by the Roman army led by Titus Flavius and the estimated death or exile of 600,000 to 1,300,000 Jews.
135 - 220 AD: Late Roman Period - Romans join the province of Iudaea (comprising Samaria, Judea proper, and Idumea) with Galilee to form new province of Syria Palaestina. Many Jews left the country altogether for the Diaspora communities, and large numbers of prisoners of war are sold as slaves throughout the Empire.
220–330 AD Late Roman Period 330 - 638 AD: Byzantine Period - Byzantines rename the entire geographic area as Palaestina ("Palestine"). In year 438 AD, Empress Eudocia allows Jews to return to Jerusalem to live.
638 - 750 AD: Umayyad Period (Arab Caliphate Period)
750 - 1099 AD: Period of Abbasids, Ikshidids, Fatimids, Seljuks etc.
Crusader Period 1099 - 1244: The Crusades After the fall of Jerusalem in 1187, the Crusader Kingdom survived throughout Ayyubid Period until 1291, well into Mamluk Period, but here we will consider its peak period, until AD 1244.
1187 - 1244: Ayyubid Period Saladin conquers Jerusalem The Ayyubid Sultanate, founded by Saladin, controlled Jerusalem and some but not all of the region until 1250, when it was defeated by the Mamluk Sultanate of Egypt.
AD 1244 - 1517: Mamluk Period After the Mongols decimated Baghdad and Damascus in the mid-1200s, the center of Islamic power moved to Cairo, under the Egyptian slave warriors, the Mamluks. They destroyed all towns on the flat coastal plains in order to rid the land of the Crusader presence and make sure it never returned. The main exceptions were Jaffa, Gaza, Lydda and Ramle. The last major Crusader stronghold, Acre fell in 1291, at the Siege of Acre. As a result of this, most trade with the west was curtailed.
1517-1917: Ottoman Period - Napoleon of France briefly waged war against the Ottoman Empire (allied then with Great Britain). His forces conquered and occupied cities in Palestine, but they were finally defeated and driven out by 1801. In the 1830's Egypt conquered Palestine and made some minor improvements and many Egyptians, in particular soldiers, settled there. It was however during this period that the Jews of Safed were massacred in 1831 by Druzes. Safed was resettled with Kurds and Algerians. This was followed in 1837 by earthquakes in Safed and Tiberias. In 1838 Palestine was given back to the Turks.
1917 - 1948: British Mandate Period By 1920, the Jewish population of Palestine had reached 11% of the population.
1948 to present: State of Israel
