Christianity Spreads and Institutionalizes – (c. 1-400 CE) (jan 1, 1 – jan 1, 400)
Description:
Despite early persecution, Christianity gained traction across the Roman Empire, especially among marginalized communities. By the 4th century, Emperor Constantine legalized the religion, and it became the empire’s official faith. The church developed doctrines like the Trinity and established a structured hierarchy. Christianity’s institutionalization allowed it to shape European politics, law, and culture for centuries to come.
