According to The Bible, Rehoboam succeeded his father, Solomon, as king of a great united empire, but was not a good leader. He continue his father's unwise policy of swingeing taxes and then arrogantly increased them when the Israelites complained. In a very short time, the Israelites rebelled and he lost an empire, the United Monarchy of Israel. On this view, the split occurred around 921 BCE.
However, it is reported that a majority of scholars believe that there never was a United Monarchy of Israel. They say that Israel and Judah were always separate, with their own customs and even different dialects of the Hebrew language. Arguably, the biblical authors created a United Israel in order to instil national unity and national pride, in a time of great difficulty for Judah, and they needed an explanation as to why this great empire ceased to exist. Rehoboam and his lack of proper leadership were the convenient explanation.
In about 926BC, Israel split into two kingdoms: Israel (in the north) and Judah (in the south)
After Solomon's death, Israel split into the two kingdoms of Judah and Israel. Israel now had ten tribes and Judah had two.

You aren't; he was a king over Israel before it split into the two kingdoms of Judah and Israel
Nowadays, Israel is not divided into two kingdoms, but thousands of years ago, Israel was split into two kingdoms called "Yehuda" and "Israel". Both kingdoms were Jewish and both had their own ledership, but only one kingdom, "Yehuda", was oficially ruling the land of Israel and Jerusalem
The split between Israel and Judah occurred around 930 BCE after the death of King Solomon, following a succession crisis. Israel fell to the Assyrians in 722 BCE and Judah later to the Babylonians in 586 BCE.
After the split of the Kingdom of Israel, the two southern tribes that formed the Kingdom of Judah were Judah and Benjamin. This division occurred around 931 BCE, following the reign of King Solomon, leading to the establishment of two separate kingdoms: Israel in the north and Judah in the south. The Kingdom of Judah maintained its capital in Jerusalem and was known for its lineage of Davidic kings.
After King Solomon's death, Israel separated into two Kingdoms - the Northern Kingdom of Israel which consisted primarily of 10 of the 12 tribes of Israel, and the Southern Kingdom of Judah which consisted primarily of tribe of Judah and Benjamin. It should be noted however, that each Kingdom had members of all 12 tribes of Israel.
The two new kingdoms that emerged were the Kingdom of Israel in the north, with Samaria as its capital, and the Kingdom of Judah in the south, with Jerusalem as its capital.
