Aside from England, the other nations which influenced colonization in the Atlantic Coast of North America were the French, Swedish, Dutch and Spanish. Early possessions of the Europeans in North America included Spanish Florida, Spanish New Mexico, the English colonies of Virginia (with its North Atlantic offshoot, Bermuda) and New England. Also included in this list are the following: the French colonies of Acadia and Canada, the Swedish colony of New Sweden, and the Dutch New Netherland. In the 18th century, Denmark–Norway revived its former colonies in Greenland, while the Russian Empire gained a foothold in Alaska. Starting in the 1600s, Denmark- Norway would later make several claims. It is because of the growing interest in the American colonization that the competitions became fierce particularly when it comes to conquering territories. Competition became more intense that it came to events where colonists encountered threats from neighboring colonies and at the same time attacks from indigenous tribes and pirates.
