Final answer:
During the 1970s and 1980s, Israeli Jews built many housing settlements in the West Bank region, increasing from about 5,000 to over 200,000 residents. These controversial settlements were part of Israel's ongoing efforts to accommodate the influx of Jewish migrants, influenced by the Zionist movement and the aftermath of the Holocaust.
Step-by-step explanation:
During the 1970s and the 1980s Israeli Jews built lots of housing settlements, especially in the West Bank. These settlements have been a subject of controversy, as the expansion took place in areas with significant Palestinian populations who opposed the settlements. In 1977, the Jewish population in West Bank settlements was about 5,000. However, by 2010, this number had increased to more than 200,000. The establishment of these settlements was part of a broader context including the migration of Jewish people to Israel, following the Zionist movement's ideology that Jews needed their own homeland, which gained urgency after the Holocaust.
