The seizure of Kent Island by Maryland governor Leonard Calvert in the winter of 1638-1639 was rooted in a disputed territorial claim between William Claiborne and the Calverts over control of the island. Claiborne had established a trading post on Kent Island, but Calvert's action to seize it represented the colonial government's assertion of authority over the territory. This dispute became a focal point of broader tensions within Maryland, including religious conflict between the Catholic minority elite and the Protestant majority, as well as political divisions stemming from the English Civil War.
In 1644, William Claiborne led an uprising of Protestants to reclaim Kent Island from Maryland's control. This uprising coincided with Richard Ingle's broader coup attempt against the government based at St. Mary's City. Although Claiborne and Ingle were not officially allied, they took advantage of the same period of instability to seize property and pillage across Kent Island and the surrounding region. The period became known as the Plundering Time (1644-1646), also called "Claiborne and Ingle's Rebellion," characterized by civil unrest and lawlessness throughout the colony.
The conflict reflected the intersection of personal disputes over land claims, religious tensions exacerbated by the English Civil War, and the political instability of the era. The fact that the period lasted from 1644 to 1646 demonstrates the sustained nature of the unrest and the difficulty colonial authorities faced in maintaining order during this turbulent time in Maryland's history.
European colonization of North America accelerated after 1600, with England, France, Spain, and the Netherlands establishing competing settlements along the Atlantic coast, the St. Lawrence River, the Gulf of Mexico, and the Mississippi Valley. The first permanent English settlement at Jamestown, Virginia (1607) struggled with starvation and conflict; the Plymouth colony (1620) and the Massachusetts Bay Colony (1630) followed. By the mid-1700s, thirteen English colonies stretched along the Atlantic seaboard, governed through a mix of royal charters, proprietary grants, and elected assemblies. The colonial economy depended on tobacco in Virginia and Maryland, rice and indigo in the Carolinas, and maritime trade in New England — all increasingly reliant on enslaved African labor after 1619. Conflict with Indigenous peoples over land was continuous, punctuated by major wars including King Philip's War (1675–1676) in New England and the Yamasee War (1715–1717) in the South. The French and Indian War (1754–1763), part of the global Seven Years' War, ended French power in North America and left Britain deeply in debt — triggering the taxation disputes that would lead to revolution.
