For the first thousand years of Christianity, there were no denominations within Christianity as there are today. Various offshoot groups certainly existed, but most were small and quickly snuffed out as "heresies."
The first major division within Christendom came in 1054, with the Great Schism between the Western Church and the Eastern Church. From that point forward, there were two large branches of Christianity, which came to be known as the Catholic Church (in the West) and the Orthodox Church (in the East).
