Final answer:
The decision by the British government that led to American independence was a range of abuses, including taxation without representation, interference in trade, denial of trial by jury, and deprivation of self-rule, as stated in the Declaration of Independence.
Step-by-step explanation:
The British government's decisions that ultimately led the American colonists to declare independence were multifaceted. According to the Declaration of Independence, primarily drafted by Thomas Jefferson as a cornerstone document of the American Revolution, it was a combination of abuses that prompted the colonies to separate from Britain. Central to the grievances were that the British monarch taxed the colonists without the consent of their locally elected representatives, interfered with trade, denied them the right to trial by jury, and deprived them of self-government.
Jefferson outlined that these actions violated the principles of sovereignty and natural rights, which were rooted in the Magna Carta and the British Bill of Rights. The colonies had developed their system of self-rule through legislative assemblies during a period known as salutary neglect, which the British government ended following the French and Indian War. A series of revenue-raising acts, including the Stamp and Sugar Acts, along with punitive measures like the Intolerable Acts, underscored the lost autonomy and escalation towards the desire for American independence.
This path to separation was also fueled by a spirit of intercolonial cooperation and growing resentment towards legislative decisions made across the ocean. The First and Second Continental Congresses were instrumental in formalizing American rights and, eventually, the unanimous (excluding New York) decision to adopt the Declaration of Independence. With this act, the colonies committed themselves to creating a new form of government free from British tyranny.
