18 THEISLAND ACADIANS Consequently, they kept their distance from political conflicts, wanting to coexist as well as possible with the authorities in power in order to ensure some degree of security. On the other hand, the Acadians showed their independence even under French rule by trading with the neighbouring colonies in New England. The survival and economic development of Acadia depended on the growth of this maritime trade. In 1710 the Acadian capital of Port Royal was captured by troops from New England. Three years later, with the Treaty of Utrecht which was concluded at the end of the War of the Spanish Succession, France ceded Hudson Bay, Acadia and Newfoundland to England. The treaty stipulated that within one year the Acadians had to leave the colony, henceforth called Nova Scotia, or remain on condition that they be- come British subjects. England guaranteed free exercise of the Catholic religion “insofar as the laws of Great Britain allowed.” Well-adapted on their land, the Acadians had no intention of relocating. Given the chronic political instability of the past hundred years, they had no reason to believe that this peace would be more lasting than previous ones. Although they refused to take the oath of allegiance to the British Crown in the form prescribed, the Acadians stated that they were willing to become British subjects provided they would not have to take up arms against France in the event of war. In addition, they wanted assurance that their Catholic faith would be respected. Several English governors of Nova Scotia tried without success to force the Acadians to take an oath of unconditional allegiance to the monarch of Great Britain. The English threatened expulsion if they refused to obey; however, neutrality meant too much for the Acadians to be able to give in to such pressures. This neutrality was put to the test during the 1740s when war broke out again between France and England. During the conflict, French troops stationed at Louisbourg tried in vain to recapture Acadia. Despite pressure from the military, most Acadians refused to join the ranks of the French army. A certain number did collaborate although nearly all of them stated afterwards that they had been forced to do so. These events prompted the British authorities to question the neutrality of the Acadians. In order to occupy her territory more efficiently England decided to send out Protestant colonists and build, in 1749, the fortress town of Halifax as a counterpoise to Louisbourg.
