back in the day, Boston was full of Irish men. The founder of the team put them in green uniform and called them the Boston Celtics. The clover design is is derived from the Irish culture, since Boston was mostly populated with Irish people.

Original team owner Walter Brown wanted a hook to try and get Boston's (at the time) large Irish population coming to home games and buying tickets ... So, he hit upon the idea of using the very Irish "Celtics" as the name. Also the team's mascot is called "Lucky the Leprechaun". Again very Irish.
Celtics celebrates the end of every harvest and the start of winter. The celebration is called Samhain. It starts on the sunset of October 31st until the sunset of November 1st.
1995- Shawmut Center 95-05- FleetCenter 05-08- TD Banknorth Garden After moving away from the old Boston Garden, the Celtics built what was to be called the Shawmut Center, after Shawmut Bank (Boston is on the Shawmut Peninsula). Shawmut was purchased by Fleet Bank and the arena was known as FleetCenter from 1995 until 2005. Fleet Bank was purchased by Bank of America who sold the naming rights to TD Banknorth. In early 2008, Banknorth was purchased by Commerce Bank. They will change the name after the 2007-08 season for the Celtics and Bruins, but have promised it will contain the word "Garden."
Celtics have won 17 championships, and Lakers 16 - the two teams with the most championships. So yes, in many ways they are the most successful franchises in the NBA.
