Question: Paragraph: The UNCRC defines children , for the purposes of the Convention , as persons under the age 18 , unless domestic legislation provides otherwise . In that spirit , this timeline includes as children all those below the UK age of majority , which was 21 until 1970 when it was reduced to 18 . Although the Crown Dependencies of the Isle of Man , Guernsey and Jersey are not constitutionally part of the UK , the British government is responsible for their external affairs and therefore for their international treaty obligations , so this timeline includes references to matters in those dependencies .

Question: Paragraph: Armed conflict began in 1775 . In 1776 , the Second Continental Congress declared the independence of the colonies as the United States of America . Led by General George Washington , it won the Revolutionary War with large support from France . The peace treaty of 1783 gave the new nation the land east of the Mississippi River ( except Canada and Florida ) . The Articles of Confederation established a central government , but it was ineffectual at providing stability , as it could not collect taxes and had no executive officer . A convention in 1787 wrote a new Constitution that was adopted in 1789 . In 1791 , a Bill of Rights was added to guarantee inalienable rights . With Washington as the first president and Alexander Hamilton his chief adviser , a strong central government was created . Purchase of the Louisiana Territory from France in 1803 doubled the size of the United States . A second and final war with Britain was fought in 1812 , which solidified national pride .
