Depending on the time, it could be the Phoenicians ( I think this is the best answer; this is what they're known for best) or later in time, the Romans (but they had colonies also elsewhere).

As a country that relies on immigrant resources as its strength, Israel's Jews have two characteristics that perhaps few other countries have, that is, adventurousness and extreme nationalism.
Since the founding of the nation, Israel has conceived that, for the national economy to really take off, three additional factors need to be added: a new wave of immigration, a new war, and a new venture capital industry.
Israel is a country that always welcomes the return of Jews around the world. As soon as they arrived in Israel the day before, the next day, they were recognized as nationals and enjoyed all the same benefits as all those who have settled here for a long time.
<h2>A. Abu Bakrؓ</h2>
The first leader of the Muslim community after Muhammad صلى الله عليه وسلم had died was Abu Bakrؓ, who became the first caliph of the Muslim community.
Among the first converts to Islam, Abu Bakrؓ generously supported Muhammad's work. During Muhammad's migration to Medina, he was one of his closest companions. In addition to this, he participated in a number of wars, such as the battles of Badr and Uhud, during his reign.
