Rehoboam for Judah and Jeroboam for Israel to begin with.
Solomon, Rehoboam, and Jeroboam were all kings in ancient Israel. Solomon was known for his wisdom and wealth, Rehoboam was Solomon's son who ruled after him and led to the split of the kingdom, and Jeroboam was the first king of the northern kingdom of Israel after the split. They were all key figures in the history of Israel.
After King Solomon died his son Rehoboam became king. The ten tribe leaders came to Rehoboam and said (I Kings 12:1-17), "Your father made our yoke heavy; now therefore lighten the burdensome service of your father, and his heavy yoke, which he put on us and we will serve you." To make a long story short Rehoboam refused and so the ten tribes broke away from the full kingdom of Israel and made a new kingdom of the northern ten tribes.
AnswerFinkelstein and Silberman (The Bible Unearthed) believe that the kingdoms of Israel and Judah were always separate, with different life styles, different pottery, different myths and legends, and even speaking different dialects of Hebrew. They insist there is no evidence the kingdoms ever were united. On this evidence, the division between Israel and Judah simply comes from their separate origins. On the other hand, the Bible says that there was once a great United Monarchy of Israel under Kings Saul, Daid and Solomon. The unwise policies and swingeing taxes of Solomon were continued under his son, Rehoboam, resulting in the rebellion of the north. The northern kingdom, known as Israel, broke away under Jeroboam, while Rehoboam continued as king of the southern kingdom of Judah.
Solomon's death resulted in the "divided kingdom". The Israelites weren't entirely happy with Solomon's extravagances, and upon his death they petitioned his son Rehoboam to institute reforms. When Rehoboam refused, the ten northern tribes (that is, all except the tribes of Judah and Benjamin) revolted and chose Jeroboam as their new king.
Rehoboam and Jeroboam were both kings in Israel's divided kingdom.
Solomon's son was Rehoboam. He succeeded Solomon as king of the United Monarchy of Israel but later faced rebellion, resulting in the kingdom being divided into the Kingdom of Israel and the Kingdom of Judah.
King Solomon had several sons, but the most notable among them were Rehoboam and Jeroboam. After Solomon's death, Rehoboam ascended to the throne, but his harsh policies led to the division of the kingdom. Jeroboam became the first king of the northern kingdom of Israel, while Rehoboam ruled over the southern kingdom of Judah. The split marked a significant turning point in the history of the Israelites.
Rehoboam for Judah and Jeroboam for Israel to begin with.
Rehoboam
The first king was Rehoboam, Solmon's son.
God punished Solomon's son, Rehoboam, by causing the kingdom of Israel to be divided after Solomon's death. Rehoboam's harsh leadership and refusal to lighten the burdens on the people led to the ten northern tribes rejecting him and forming their own kingdom, Israel, under Jeroboam, while Rehoboam continued to rule over the southern kingdom of Judah. This division marked a significant shift in the history of Israel.
Rehoboam the son of Solomon after he became king (I kings 12:1-17). This led to the splitting of Israel into the Northern Kingdom (10 tribes) and the Southern Kingdom (initiallly Judah and Benjamin and later most of Levi and some of Simeon).
Rehaboam split the kingdom. He wanted to raise taxes and Solomon's advisers advised against it. He did not listen to them instead listening to young advisers. Jeroboam came to him and asked him to lower the taxes or he would split the kingdom. Rehoboam did not listen and the kingdom was split.
According to the Bible, General Jeroboam led a successful secession from the Unified Kingdom of Israel under King Rehoboam, leading to the creation of the Northern Kingdom of Israel under King Jeroboam and the Southern Kingdom of Judah under King Rehoboam. (Yes, the entity that seceded kept the name.)
Rehoboam Another answer: Rehav'am (Rehoboam) did not conquer the Northern Kingdom. Rather, he took leadership over it when it was formed (the Ten Tribes seceded from the rule of King David's descendants). The Northern Kingdom was conquered by the Assyrian king Shalmanesser.
The people complained to the next king (Rehoboam) about the rate of taxation, and he ignored them, so some of the tribes seceded into a separate kingdom.
