Was Judah the north

A:

According to The Bible, the northern tribes broke away from the kingdom of Israel, with its capital in Jerusalem, to found a kingdom called Israel. The remnant former kingdom, still based around Jerusalem, took the name of Judah. If that sounds rather puzzling, many scholars believe there never was a United Kingdom of Israel. The respected Israeli archaeologist, Israel Finkelstein, says that the two kingdoms were always separate, with their own separate cultures and dialects of the Hebrew language.
