The Revenue Act of 1767, also referred to as the Townshend Duties, taxed glass, lead, paint, paper, and tea coming into the Anglo-American colonies. That year, wealthy landowners in Britain had used their political influence to cut their taxes by a fourth, causing a massive deficit in the British treasury. Chancellor Charles Townshend made up for this deficit via the Revenue Act.
In reality, the duties brought in very little revenue, with the exception of the taxes on tea. All they really did was provoke the colonists. Assemblies all over the colonies denounced the Act, calling for its repeal. Yet another boycott of British goods was enacted, which motivated merchants in Britain to push for the repeal of the Act as well. All this tension led to violence in the colonies, culminating in the Boston Massacre in March 1770. Parliament relented and repealed most of the Townshend Duties.
It would be very difficult to argue that one person/event can accurately summarize the huge political, social, and economic changes that took place during this era. One must consider that this time period saw the anti-war movement, civil rights movement, environmental movement, and parts of the women's rights movement. No one person or event involved all of these different changes at once.
However, if you were to make this argument you could use the following:
a) Martin Luther King Jr.- His role in the Civil Rights movement and peace movement make him one of the biggest civil rights icons of the 21st century.
b) March on Washington for Jobs and Freedom- This 1963 march included hundreds of thousands of Americans and allowed MLK to give his "I have a dream speech."
