Tammany Hall was a very powerful political group in New York City. 

As time passed, the club changed into a political machine. A political machine is a group that works to control elections. Early leaders like Aaron Burr used the group to gain political power. Burr was a famous leader who helped the group support Thomas Jefferson. Later, a man named Matthew L. Davis made the group even stronger. He created a committee that could decide who would win elections. He also started a practice of using committees to watch political friends and foes. This helped the group stay organized and stay in control of the city.
Many different kinds of people joined Tammany Hall over the years. As more immigrants moved to New York, the group grew much larger. It became especially important for Irish Catholic immigrants living in the city. Tammany helped these new residents find jobs and support in their new homes. In return, these people gave their votes to the group. This created a strong bond between the leaders and the voters. By helping people with their daily needs, the group built a massive network of loyal supporters. 
However, the group also had a reputation for being corrupt. Corruption means that people in power use their jobs to take things unfairly. One famous leader was William M. Tweed. In 1873, he was caught for embezzlement, which is taking money that does not belong to you. 

Because of this corruption, many people fought to change how the city worked. These people were called reformers. Famous reformers like Theodore Roosevelt and Franklin D. Roosevelt worked to oppose Tammany's influence. The group began to lose its power after New York City changed in 1898. It had to compete with many other local organizations for control. Changing populations in Manhattan also made it harder for the group to stay strong. Eventually, the long history of Tammany Hall came to an end when it was dissolved in 1967.
Tammany Hall was a massive political organization that shaped the history of New York City. It was known by several names, including the Society of St. Tammany and the Columbian Order. While it began as a social club, it eventually became the primary political machine for the Democratic Party. A political machine is a highly organized group that controls elections and government jobs. At its peak, Tammany Hall was synonymous with the New York County Democratic Party. It held immense power over both city and state politics for many decades. 
The organization was officially incorporated on May 12, 1789. Its name honored Tamanend, a Lenape chief from the late seventeenth century. The members adopted various Native American customs to reflect this heritage. They referred to their meeting hall as a "wigwam." They also called their leader a "grand sachem." The first grand sachem was an upholsterer named William Mooney. However, a wealthy man named John Pintard established the group's formal constitution. Pintard intended the society to be a democratic institution. He hoped it would correct the influence of the city's wealthy aristocracy. 
In its early years, the society moved from social activities toward active politics. Aaron Burr was the first leader to use the group for political gain. By 1798, the society grew more focused on supporting Jeffersonian Republicans. Burr used the group as a major asset during the presidential election of 1800. After Burr left politics, Matthew L. Davis became the leader in 1805. Davis introduced several innovations that built a true political machine. He secured a state charter for the society as a charitable organization. He also established the General Committee of Tammany Hall. This committee acted as a "kingmaker" in New York City politics. 
To maintain control, the organization developed a sophisticated system of oversight. A member named Wortman started an investigatory committee. This committee included one member from every political ward. Their job was to identify political friends and foes. They reported these findings back to general meetings to ensure loyalty. The group also focused on expanding its membership. Instead of only working with existing groups, Tammany worked to incorporate new members. They often rewarded former opponents with positions if they joined the organization. This strategy helped them grow their influence across the city.
As New York City grew, Tammany Hall changed its focus to support new residents. The immigrant population increased significantly during the nineteenth century. The organization became especially vital for Irish Catholic immigrants. Tammany leaders built a network of loyal district and precinct leaders. These leaders were often well-rewarded for their service. In exchange for help with jobs and social support, immigrants provided steady votes. This created a powerful cycle of political patronage. Patronage is the practice of giving government jobs to supporters. This system allowed Tammany to control Democratic Party nominations for over a century.
Despite its efficiency, the organization faced constant accusations of corruption. Many leaders used their power for personal gain through political graft. Graft is the dishonest use of one's position to make money. The most famous example involved William M. Tweed. In 1873, Tweed was convicted of embezzlement, which is stealing money entrusted to one's care. This scandal gave Tammany Hall a lasting national reputation for being corrupt. 

The rise of reform movements eventually led to the decline of Tammany Hall. Many politicians gained fame by fighting against the organization's influence. These reformers included famous figures like Theodore Roosevelt and Franklin D. Roosevelt. The consolidation of greater New York City in 1898 also changed the political landscape. Tammany Hall was forced to compete with many other local organizations. Changing demographics in Manhattan further weakened its traditional power base. After decades of opposition and shifting politics, the organization was finally dissolved in 1967.
