George Grenville Biography

George Grenville was a British statesman and politician who served as Prime Minister of Great Britain from 1763 to 1765. Grenville played an important role in developing legislation that was directed at the American Colonies to raise revenue for the British Treasury, specifically the Sugar Act of 1764, the Currency Act of 1764, and the Stamp Act of 1765.

The acts were intended to regulate the use of currency in the colonies and to raise revenue to help pay for the standing army in North America that was established after the French and Indian War. However, American political leaders, including James Otis of Massachusetts and Stephen Hopkins of Rhode Island, accused Grenville and Parliament of levying taxes on the colonies without representation.

The situation escalated with the passage of the Stamp Act, which caused the Stamp Act Crisis in America. During the crisis, effigies of Lord Bute and Grenville were often paraded, hung, and burned during public demonstrations.

Grenville’s policies were criticized in Parliament by leaders such as Isaac Barré. Grenville also damaged Great Britain’s relations with European nations and made many political enemies, all of which contributed to his dismissal by King George III on July 10, 1765. Grenville was replaced by Charles Watson-Wentworth, the 2nd Marquess of Rockingham.

George Grenville and the Beginning of the American Revolution

Prime Minister of England

Grenville succeeded John Stuart, the 3rd Earl of Bute, as Prime Minister of Great Britain on April 16, 1763. Bute resigned from the position due to opposition to his policies and growing unpopularity. One of Bute’s controversial decisions regarding the American Colonies was the establishment of a standing army of 10,000 troops in North America after the French and Indian War. As Prime Minister, Grenville ended up overhauling the financial system of the colonies by completely altering the relationship between the colonies and Britain through a series of ill-fated reforms. Each of his reforms, which were achieved through a series of bills passed by Parliament and approved by King George III, were, in fact, direct causes of the American Revolution.

Pontiac’s Rebellion and the Proclamation of 1763

Soon after Grenville took office, Pontiac’s Rebellion started in the Great Lakes Region of North America. It was a loosely-planned uprising of Native American Indian tribes who were upset over the provisions of the 1763 Treaty of Paris and the treatment they received from British officials in North America. Indian warriors attacked British forts and settlements throughout the region. In an effort to end the uprising, King George III issued the Proclamation of 1763 which reserved the territory as hunting grounds for the tribes. However, it also restricted the westward expansion of the colonies. The threat of another uprising by the Indians and the need to enforce the Proclamation of 1763 justified the need for a standing army, even though Americans disagreed. However, to pay for the army, Grenville needed to find ways to raise money to cover the costs.

Grenville Ends Salutary Neglect and Reforms Customs

Grenville and the Lords of the Treasury looked at different ways to raise money to help pay for the army in North America. It was decided the best option was to raise money from the American Colonies. To do that, Grenville ended the long-standing policy of Salutary Neglect and directed British customs officials to start enforcing the Navigation Acts — especially the Molasses Act of 1733 — on American merchants.

In order to enforce the Navigation Acts, Grenville overhauled the British customs service. In order to force customs commissioners to collect taxes, he required them to live in the colonies. Before that, a customs commissioner usually lived in England and paid someone else to live in the colonies and perform the duties of the job. Grenville also authorized the Royal Navy to help enforce the Navigation Acts. The Vice-Admiralty courts were also given jurisdiction over court cases that dealt with smuggling and violations of the Navigation Acts.

Grenville Introduces the Sugar Act of 1764

Grenville introduced his budget to Parliament on March 9, 1764, which included new and revised taxes related to the Molasses Act. Those provisions were collected together into one bill, known as the Sugar Act. It was passed by the House of Commons and House of Lords and received Royal Assent from King George III on April 5, 1764. The Sugar Act was the first revenue act passed by Parliament for the purpose of raising money from the American Colonies. As far as the colonists were concerned, it was the first law from Parliament that levied “taxation without representation.”

During the speech that introduced the Sugar Act, Grenville also hinted at another law that would be needed in order to raise enough money — a stamp tax.

Grenville Takes Control of Colonial Currency

The next step in Grenville’s financial plan was to eliminate paper money that was used in some of the American Colonies. Parliament passed the Currency Act on April 19, 1764. Under the provisions of the act, Parliament essentially took control of currency in Colonial America on September 1, 1764. Parliament had already abolished paper money in New England and the Currency Act extended the policy to the rest of the colonies.

The bill was created to force American merchants to pay British merchants with specie — gold and silver — instead of paper money, which fluctuated in value. The main problem with the Currency Act was it required debts to be paid with gold and silver, which was in short supply in the colonies.

Americans Respond to the Sugar Act and Currency Act

Americans protested the Sugar Act, primarily through economic and political means, and often those protests included arguments against being forced to pay with gold and silver. 

During this time, Samuel Adams rose to prominence and joined with James Otis as a leader in Massachusetts against British policies.

The passage and enforcement of the Sugar Act contributed to the growth of an ideological movement in Colonial America that help fuel the American Revolution. The ideas behind the slogan “no taxation without representation” were key arguments against Grenville’s taxation policies in regard to the American Colonies.

Grenville Orchestrates the Stamp Act

Following on the heels of the Sugar Act and Currency Act, Grenville started working on the Stamp Act. The bill was drafted by Thomas Whately, and both Whately and Grenville discussed it with some of the agents for the colonies, including Benjamin Franklin, Jarod Ingersoll of Connecticut, and William Knox of Georgia. Despite objections to the act, the agents were unable to present an alternative, so Grenville moved ahead with the Stamp Act, which was introduced to the House of Commons on February 6, 1765. During that session, Isaac Barré criticized the bill and referred to the Americans who were speaking out against taxation as “sons of liberty.” Despite Barré’s protest, the bill passed both Houses of Parliament. It received Royal Assent on March 22 and was scheduled to take effect on November 1, 1765.

The Stamp Act required all legal documents and many printed materials, including newspapers pamphlets, and playing cards, to be printed on paper that was embossed with a special stamp. Americans would have to buy the stamped paper from designated Stamp Distributors — and would have to buy it with gold and silver — per the requirements of the Currency Act.

The Stamp Act Crisis

Americans found out in April the Stamp Act passed, and almost immediately started to speak out against it. Many Americans felt it was possible to convince Parliament to repeal the act before it went into effect on November 1. 

As with the Sugar Act, Americans protested with political and economic means. Virginia passed the Stamp Act Resolves, and several other colonies followed suit, including Massachusetts and New Jersey. Massachusetts sent a circular letter that called for an intercolonial conference, which was held in New York in October.

However, opposition to the Stamp Act turned violent and carried out into the streets. Those protests — the Stamp Act Riots — often included mobs that burned effigies of Bute and Grenville. Some of them targeted British officials, including Lieutenant Governor Thomas Hutchinson of Massachusetts. Others targeted the Stamp Agents, who were often threatened with violence and forced to publicly resign. The riots and public demonstrations were usually carried out by groups that eventually referred to themselves as the “Sons of Liberty.”

In October, the Stamp Act Congress met in New York and produced the “Declaration of Rights and Grievances” that asserted Parliament did not have the authority to tax the colonies.

During the Stamp Act Crisis, the ideals of the American Revolution were formed and came to the forefront of the Patriot Cause. The crisis also brought several Patriot leaders to the forefront, including Patrick Henry and Christopher Gadsden.

The Quartering Act of 1765

One final controversial act that was passed under the Grenville Ministry had nothing to do directly with fiscal reform, but it did deal with helping to defray the cost of the army. On March 24, 1765, Parliament passed the Quartering Act of 1765, which required a colonial legislature to provide money to cover the cost of basic needs, such as bedding, cooking utensils, firewood, beer or cider, and candles for troops that were stationed in its colony. 

At the time, the only colony troops were stationed in was New York. After the Stamp Act was passed, the New York Sons of Liberty, led by Isaac Sears, John Lamb, and Alexander McDougall, formed and organized resistance to British policy. Not only did the Sons of Liberty antagonize the Redcoats, but some of them were also members of the New York Assembly. At first, the New York Assembly refused to provide the money needed for the expenses, which upset the soldiers and British officials.

Over time, the presence of troops in New York raised tensions between the citizens of the city and the Redcoats. In 1770, it led to the Battle of Golden Hill, an incident where British troops attacked New Yorkers in the streets of the city. It took place in January — roughly six weeks before the Boston Massacre.

The End of the Grenville Ministry

In the spring of 1765, King George III was sick and could not perform his duties. Grenville introduced the Regency Bill, which specified a member of the Royal Family should act in the King’s place if he was incapacitated for a lengthy amount of time. Despite the good intentions, King George III was upset. Further complicating matters was the fact the silk weavers in Britain were rioting and protesting against domestic policies. King George III simply had enough of Grenville and decided to replace him. On July 13, 1765, in the midst of the Stamp Act Crisis, Charles Watson-Wentworth, the 2nd Marquis of Rockingham, took the office.
