The concept of Hamilton first came to Lin-Manuel Miranda after picking up a copy of Alexander Hamilton by Ron Chernow at an airport. After finishing the first couple of chapters, he quickly imagined Hamilton’s life as a musical. He later began working on a project called The Hamilton Mixtape. On May 12, 2009, he was invited to perform music from his hit Broadway show “In the Heights” at the White House. Instead, he performed the first song from his “Mixtape,” being a rough version of the song “Alexander Hamilton.” After that, he spent a year working on the song “My Shot.”
On July 27, 2013, Lin-Manuel performed in a workshop production of the show, which was called back then as “The Hamilton Mixtape.” The workshop consisted of the entire first act and three songs from the second act.
The show began previews Off-Broadway on January 20, 2015, and officially starting on February 17. The show later relocated to the Richard Rodgers Theater in New York, the same theater where “In the Heights,” debuted on 2008. The Broadway production was met with universal claim earning 16 Tony Nominations and winning 11 including Best Musical and Best Book of a Musical. The original cast recording for Hamilton was released digitally on September 21, 2015. It debuted number 12 on the Billboard 200 albums chart, the highest entrance for a cast recording since 1963. It went on to reach number 3 on the Billboard 200.
Most of the work done for the musical, such as playwriting, directing, acting, composing, was done by Lin Manuel Miranda. The song "You'll be Back" sung by King George was written by Lin Manuel during his honeymoon back in 2010. Jonathan Groff, who played as the original King George, describes this song as "a throwback to sixties Beatles tune". Manuel also calls this song the "Break-up Song" since it depicts the independence of America from England.
