And the beginning of his kingdom was Babel, and Erech, and Accad, and Calneh, in the land of {g} Shinar.

(g) For there was another city in Egypt, called Babel.

Wesley's Notes

10:10 The beginning of his kingdom was Babel - Some way or other, he got into power: and so laid the foundations of a monarchy which was afterwards a head of gold. It doth not appear that he had any right to rule by birth; but either his fitness for government recommended him, or by power and policy he gradually advanced into the throne. See the antiquity of civil government, and particularly that form of it which lodges the sovereignty in a single person.

Babel: Gr. Babylon

Jamieson-Fausset-Brown Bible Commentary

10. the beginning of his kingdom-This kingdom, of course, though then considered great, would be comparatively limited in extent, and the towns but small forts.

Matthew Henry's Concise Commentary

10:8-14 Nimrod was a great man in his day; he began to be mighty in the earth, Those before him were content to be upon the same level with their neighbours, and though every man bare rule in his own house, yet no man pretended any further. Nimrod was resolved to lord it over his neighbours. The spirit of the giants before the flood, who became mighty men, and men of renown, Ge 6:4, revived in him. Nimrod was a great hunter. Hunting then was the method of preventing the hurtful increase of wild beasts. This required great courage and address, and thus gave an opportunity for Nimrod to command others, and gradually attached a number of men to one leader. From such a beginning, it is likely, that Nimrod began to rule, and to force others to submit. He invaded his neighbours' rights and properties, and persecuted innocent men; endeavouring to make all his own by force and violence. He carried on his oppressions and violence in defiance of God himself. Nimrod was a great ruler. Some way or other, by arts or arms, he got into power, and so founded a monarchy, which was the terror of the mighty, and bid fair to rule all the world. Nimrod was a great builder. Observe in Nimrod the nature of ambition. It is boundless; much would have more, and still cries, Give, give. It is restless; Nimrod, when he had four cities under his command, could not be content till he had four more. It is expensive; Nimrod will rather be at the charge of rearing cities, than not have the honour of ruling them. It is daring, and will stick at nothing. Nimrod's name signifies rebellion; tyrants to men are rebels to God. The days are coming, when conquerors will no longer be spoken of with praise, as in man's partial histories, but be branded with infamy, as in the impartial records of the Bible.
