While the exact year that line dancing began is unknown, it potentially had its beginning in America in the 1800s with the old "contra" style of dancing. This style rose to popularity in the New England states.
In the 1800s, line dances were performed in two lines in which dancers faced one another, and partners danced down the center of the lines one at a time. When they reached the end of the line, the next set of partners progressed down the center. The form of line dancing practiced today began in the 1970's when more complex dances were beginning to be choreographed. These included "The Traveling Four Corners" dance, which changed the form of the line dance into a square dance while still keeping the same concepts as the original line dance.
