1634 · St. Clement's Island, Maryland, USA
Founding of Maryland as a Catholic Colony
In 1634, English Catholic colonists established Maryland under a charter granted to the Calvert family, creating the first English colony where Catholics could worship freely and pioneering religious toleration in America.
George Calvert, the first Lord Baltimore, was a convert to Catholicism who had given up his position as Secretary of State because English law barred Catholics from holding office. He wanted to establish a colony where Catholics could live and worship without penalty. He died before the charter was finalized, but his son Cecil, the second Lord Baltimore, carried the project forward. On March 25, 1634, the feast of the Annunciation, two ships — the Ark and the Dove — arrived at what is now St. Clement's Island in the Potomac River. The roughly 150 colonists included both Catholics and Protestants, and one of the first acts on shore was the celebration of Mass by Father Andrew White, a Jesuit who had organized the spiritual dimensions of the expedition. From the beginning, Maryland was designed as an experiment in coexistence. The Calverts were practical. They knew that a purely Catholic colony would be politically vulnerable in the Protestant British Empire, so they insisted on toleration. In 1649, the Maryland Assembly passed the Act Concerning Religion, often called the Toleration Act, which protected the rights of all Christians to worship freely. It was not perfect by modern standards — it applied only to Christians and prescribed the death penalty for denying the Trinity — but it was ahead of its time. The experiment faced constant pressure. Puritans gained control of the colony in the 1650s and briefly repealed the act. After the Glorious Revolution of 1688, the Church of England became the established religion in Maryland, and Catholics were once again subject to penal laws. But the precedent had been set. When the American founders debated religious freedom a century later, Maryland's example was part of the conversation.
Why it matters
Established the first English-speaking colony with legal protections for Catholic worship and pioneered the principle of religious toleration that would later influence the American approach to religious freedom.
What Happened
On March 25, 1634, English Catholic and Protestant colonists arrived at St. Clement's Island in present-day Maryland aboard the Ark and the Dove. The colony was established under a royal charter granted to the Calvert family, who were Catholic. Father Andrew White, a Jesuit, celebrated Mass upon landing. The colony was deliberately designed for religious coexistence, and in 1649 its assembly passed one of the earliest legal protections for religious freedom in the English-speaking world.
Why It Still Matters
Maryland's founding is the origin point of Catholic life in the United States. The colony demonstrated that Catholics could build a functioning society that respected religious diversity, countering the widespread assumption that Catholic rule meant intolerance. Although the experiment was eventually overturned by Protestant political power, the precedent endured. American Catholics point to Maryland when arguing that religious liberty is not just a Protestant idea but a Catholic one, rooted in their own colonial history.
