Chariots drawn by either 2 or 4 horses raced here representing one of the four factions divided among the people. Each faction was represented by a color.
Later on these four colors were united in two colors; the Blues and the Greens. The Blues were the upper and middle classes, orthodox in religion and conservative in politics. The Greens were the lower class and radical both in religion and politics.
One of these political divisions ended with a revolt which caused the death of 30,000 people. This revolt was named after people's cries of "nika" which meant "win" and this Nika Revolt took place in 531 AD.
The central axis of the hippodrome was called spina and the races took place around the spina. The races used to start by the order of the emperor and the contestants had to complete seven laps around the spina. The winner was awarded a wreath and some gold by the emperor.
The hippodrome was destroyed and plundered in 1204 by the Crusaders. After the Turks it lost its popularity and especially with the construction of the Blue Mosque, the ancient hippodrome changed its name and became At Meydani (Horse Square) a place where Ottomans trained their horses.
The only three remaining monuments from the original building are the Egyptian Obelisk, the Serpentine Column and the Constantine Column.
