Learn More About It

The original thirteen colonies became states when they declared their independence from Great Britain. From that time on, they would govern themselves. Becoming a state was also a big step for all the other states that would join the Union. They became states when their population was large enough and when they were ready to write their own laws. When states were admitted to the Union, they also began to send representatives to the national Congress. Those representatives help govern the nation as a whole.
