Final answer:
The Proclamation of 1763 and the Stamp Act both created discontent in the colonies and growing support for revolution.
Step-by-step explanation:
The Proclamation of 1763 and the Stamp Act were similar in their contributions during the colonial period as both created discontent in the colonies and growing support for revolution.
The Proclamation of 1763 was issued by the British to regulate westward expansion and prevent conflicts with Native American tribes. It prohibited colonial settlement beyond the Appalachian Mountains, which angered many colonists who wanted to expand their land holdings.
The Stamp Act, on the other hand, imposed direct taxes on the colonists by requiring them to purchase stamps for various printed materials. This was the first time the colonists were directly taxed by the British government, without their consent. The Stamp Act led to widespread protests and the famous slogan 'no taxation without representation,' which highlighted the colonists' desire for self-governance.
