Porfirio Diaz was president of Mexico from 1884 to 1911, This was a time of great economic growth for Mexico, as the regime opened its doors to foreign investment, particularly in the mining sector. However, Diaz's policies promoted a strong centralized government, which would lead to an unequal focus on certain regions and economic activities of the country, leaving others exposed to impoverishment. The expropriation of peasants lands in favor of big enterprises enraged rural populations. Inequality among the regions and societies of urbanized areas was becoming more evident. This led to a series of manifestations against the government that would eventually lead to the end of the regime.
After almost two thousand years of life in the scattering, the Jews began to return to Israel after the Second World War. It was preceded by many agreements, promises, that by the decision of the UN, the Jews would be allowed to form their own state in Palestine. Of course this did not go without conflicts and struggle, because the Arabs who had already lived in Palestine claimed that Palestine had been their land for many centuries, calling on mosques that exist on the hill of the temple. On the other hand, the Jews claimed that Palestine was actually Israel, their promised land according to the Bible, and called for a crying wall, the remains of the Jewish temple, which according to the Bible existed before the Arabs were in Palestine.
The answer is: Jews and Arabs.
