How did Ruthord B Hayes become president?

Rutherford B. Hayes became president after a highly contested election in 1876 against Samuel J. Tilden. Tilden initially appeared to have won the election, but disputes over electoral votes in several states led to a deadlock. To resolve the crisis, Congress established a bipartisan Electoral Commission, which ultimately awarded Hayes the presidency by a narrow margin. His inauguration in 1877 was part of a compromise that included the withdrawal of federal troops from the South, effectively ending Reconstruction.
