Presbyterianism first officially arrived in Colonial America in 1703 with the establishment of the first Presbytery in Philadelphia. In time, the presbytery would be joined by two more to form a synod (1717) and would eventually evolve into the Presbyterian Church in the United States of America in 1789. The nation's largest Presbyterian denomination, the Presbyterian Church (U.S.A.) – PC (USA) – can trace their heritage back to the original PCUSA, as can the Presbyterian Church in America (PCA), the Orthodox Presbyterian Church (OPC), the Bible Presbyterian Church (BPC), the Cumberland Presbyterian Church (CPC), the Cumberland Presbyterian Church in America the Evangelical Presbyterian Church (EPC) and the Evangelical Covenant Order of Presbyterians (ECO).
