About

Each marker links to its Wikipedia article for deeper reading. Settlement shading shows where colonists were actually settled versus territory that remained under Indigenous control or was disputed at the time. Use the time slider above to see who controlled the territory on any date — note that Maine was part of Massachusetts from 1658 until statehood in 1820.
