What event made the Compromise of 1877 possible?

The Compromise of 1877 was an informal agreement between southern Democrats and allies of the Republican Rutherford Hayes to settle the result of the 1876 presidential election and marked the end of the Reconstruction era.

i do not know if this question has options, but a main impact of the federal reserve act of 1913, which created the federal reserve bank, was the international use of the u.s. dollar, which soon became the world's leading currency - particularly during world war i, since many nations around the world asked the united states for money.

not really sure i needed the points. sorry
