The Sea of Galilee, also Kinneret, Lake of Gennesaret, or Lake Tiberias is a freshwater lake in Israel. It is approximately 53 km (33 mi) in circumference, about 21 km (13 mi) long, and 13 km (8.1 mi) wide. Its area is 166.7 km2 (64.4 sq mi) at its fullest, and its maximum depth is approximately 43 m (141 feet). At levels between 215 metres (705 ft) and 209 metres (686 ft) below sea level it is the lowest freshwater lake on Earth and the second-lowest lake in the world (after the Dead Sea, a saltwater lake). The lake is fed partly by underground springs although its main source is the Jordan River which flows through it from north to south.

Geography:
Sea of Galilee in relation to the Dead Sea
The Sea of Galilee is situated in northeast Israel, between the Golan Heights and the Galilee region, in the Jordan Rift Valley, the valley caused by the separation of the African and Arabian Plates. Consequently, the area is subject to earthquakes, and in the past, volcanic activity. This is evident by the abundant basalt and other igneous rocks that define the geology of the Galilee

History:
Prehistory:
In 1989, remains of a hunter-gatherer site were found under the water at the southern end. Remains of mud huts were found which are the oldest known buildings in the world. See Ohalo. Nahal Ein Gev, located about 3 km east of the lake, contains a village from the late Natufian period. The site is considered one of the first permanent human settlements in the world from a time predating the Neolithic revolution.

Antiquity:

The Sea of Galilee lies on the ancient Via Maris, which linked Egypt with the northern empires. The Greeks, Hasmoneans, and Romans founded flourishing towns and settlements on the land-locked lake including Hippos and Tiberias. The first-century historian Flavius Josephus was so impressed by the area that he wrote, "One may call this place the ambition of Nature"; he also reported a thriving fishing industry at this time, with 230 boats regularly working in the lake. Archaeologists discovered one such boat, nicknamed the Jesus Boat, in 1986.

Much of the ministry of Jesus occurred on the shores of Lake Galilee. In those days, there was a continuous ribbon development of settlements and villages around the lake and plenty of trade and ferrying by boat. The Synoptic gospels of Mark (1:14–20), Matthew (4:18–22), and Luke (5:1–11) describe how Jesus recruited four of his apostles from the shores of Lake Galilee: the fishermen Simon and his brother Andrew and the brothers John and James. One of Jesus' famous teaching episodes, the Sermon on the Mount, is supposed to have been given on a hill overlooking the lake. Many of his miracles are also said to have occurred here including his walking on water, calming the storm, the disciples and the miraculous catch of fish, and his feeding five thousand people (in Tabgha). In John's Gospel the sea provides the setting for Jesus' third post-resurrection appearance to his disciples (John 21).

In 135 CE, Bar Kokhba's revolt was put down. The Romans responded by banning all Jews from Jerusalem. The center of Jewish culture and learning shifted to the region of the Galilee and the Kinneret, particularly the city of Tiberias. It was in this region that the Jerusalem Talmud was compiled.

Middle Ages:
The lake's importance declined when the Byzantines lost control and the area was conquered by the Umayyad Caliphate and subsequent Islamic empires. Apart from Tiberias, the major towns and cities in the area were gradually abandoned.[citation needed] The palace Khirbat al-Minya was built by the lake during the reign of the Umayyad caliph al-Walid I (705–715 CE). In 1187, Saladin defeated the armies of the Crusades at the Battle of Hattin, largely because he was able to cut the Crusaders off from the valuable fresh water of the Sea of Galilee.

Modern era:
Throughout the early Ottoman era, the lake had little importance within the Ottoman Empire. Tiberias did see a significant revival of its Jewish community in the 16th century, but had gradually declined, until in 1660 the city was completely destroyed. In the early 18th century, Tiberias was rebuilt by Zahir al-Umar, becoming the center of his rule over Galilee, and seeing also a revival of its Jewish community.

In 1909, Jewish pioneers established the first cooperative farming village (kibbutz), Kvutzat Kinneret in the immediate vicinity of the lake. The settlement trained Jewish immigrants in farming and agriculture. Later, Kvutzat Kinneret pioneers established Kibbutz Degania Alef. The Kvutzat Kinneret is considered the cradle of the kibbutz culture of early Zionism and is the birthplace of Naomi Shemer and the burial site of Rachel—two of the most prominent Israeli poets.

In 1917, the British defeated Ottoman Turkish forces and took control of Palestine, while France took control of Syria. In the carve-up of the Ottoman territories between Britain and France, it was agreed that Britain would retain control of Palestine, while France would control Syria. However, the allies had to fix the border between the Mandatory Palestine and the French Mandate of Syria. The boundary was defined in broad terms by the Franco-British Boundary Agreement of December 1920, which drew it across the middle of the lake. However, the commission established by the 1920 treaty redrew the boundary. The Zionist movement pressured the French and British to assign as many water sources as possible to Mandatory Palestine during the demarcating negotiations. The High Commissioner of Palestine, Herbert Samuel, had sought full control of the Sea of Galilee. The negotiations led to the inclusion into the Palestine territory of the whole Sea of Galilee, both sides of the River Jordan, Lake Hula, Dan spring, and part of the Yarmouk.  The final border approved in 1923 followed a 10-meter wide strip along the lake's northeastern shore, cutting the Mandatory Syria (State of Damascus) off from the lake.

The British and French Agreement provided that existing rights over the use of the waters of the Jordan by the inhabitants of Syria would be maintained; the Government of Syria would have the right to erect a new pier at Semakh on Lake Tiberias or jointly use the existing pier; persons or goods passing between the landing-stage on the Lake of Tiberias and Semakh would not be subject to customs regulations, and the Syrian government would have access to the said landing-stage; the inhabitants of Syria and Lebanon would have the same fishing and navigation rights on Lakes Huleh, Tiberias and River Jordan, while the Government of Palestine would be responsible for policing of lakes.

On May 15, 1948, Syria invaded the newborn State of Israel,  capturing territory along the Sea of Galilee. Under the 1949 armistice agreement between Israel and Syria, Syria occupied the northeast shoreline of the Sea of Galilee. The agreement, though, stated that the armistice line was "not to be interpreted as having any relation whatsoever to ultimate territorial arrangements." Syria remained in possession of the lake's northeast shoreline until the 1967 Arab-Israeli war.

In the 1950s, Israel formulated a plan to link the Kinneret with the rest of the country's water infrastructure via the National Water Carrier, in order to supply the water demand of the growing country. The carrier was completed in 1964. The Israeli plan, in line with the Headwater Diversion Plan (Jordan River) of the Arab League, sparked political and sometimes even armed confrontations over the Jordan River basin.
