Various Zionist organizations bought land from large Arab land owners, often absentee landlords living in other Arab countries. Israelis never sold land. They bought it, cleared it, drained, farmed it, and held it in trust for current and future settlers.
Much Arab land was converted to Israeli property by legal means. Should Arabs not have wanted Jews in "Palestine" they would not have sold them their land.
The Jews started legally purchasing the swampland and deserts of unoccupied Palestine around the beginning of the 20th Century, and they converted into livable land.
The Jewish occupation of Palestine was gradual, taking almost a century before they proclaimed independence for what would henceforth be known as the nation of Israel.
On eve of Crimean War(1853-56) only about 20,000 Jews lived in Palestine. Legal and illegal Immigration resulted in the Jewish population growing to around 600,000 by 1947. Most of the native Palestinians were driven out of Israeli-controlled areas into what are now known as the Palestinian Territories or into refugee camps in Lebanon, Syria and Jordan.

No. For most of the last 2,000 years, the Jews in Palestine were a repressed minority (or on occasion a repressed majority). Probably the most bloody period for Jews in Palestine was during the Crusades when Christian leaders slaughtered numerous Jews, especially in Jerusalem. However, Jews suffered other calamities in Palestine, such as the destruction of both Great Temples and the exile of significant portions of the Jewish population.
