Since the initial impetus to collect, preserve, and interpret history with the intent of safeguarding American heritage for posterity, historical societies have made substantial contributions to the preservation of historical records. Historical societies have tended to originate in socially exclusive groups and found history museums, celebratory in nature. In contemporary society, this exclusivity raises issues and concerns for contemporary institutions seeking to "serve the public." Tempe History Museum, Chandler Museum, and Scottsdale Historical Museum are examples of local history museums, initially formed by historical societies, which are currently at different stages of developing exhibits and collections more representative of their diverse communities. The three museums have different approaches to not only defining their local community but also to what it means to serve and represent their city by being the local history museum. In recent years, the Tempe History Museum has undergone a renovation of its facility and exhibits, the Chandler Museum is in the midst of transferring its collection to the City of Chandler and planning for a new facility, and the Scottsdale Historical Museum has remained largely the same since the early 1990s. The decisions made by the historical societies that found these museums have shaped and directed the museums' paths to becoming, or failing to become, relevant to their local communities. The Tempe, Chandler, and Scottsdale historical societies came from the Anglo-community within each city, so did the collections they acquired and the objects they displayed. At a time of rising social history, the historical societies presented socially exclusive museums. Becoming incorporated within the city government, would prove to be the point of change, the tipping point when the history museums moved from particularism to pluralism. The change, however, did not come overnight. It was change over time. The city governments had an obligation to equally represent its taxpayers and constituency, meaning that the newly incorporated museums had to eventually follow the same mission. In the case of Tempe, Chandler, and Scottsdale museums, incorporation within city governments has led to a stable funding source, professional staff, and a move towards representation of diverse communities within museum exhibits and programming.
