The Cleveland Browns moved to Baltimore in 1996 after stadium issues with the city of Cleveland. Cleveland was allowed to keep the "Browns" intellectual property, name, team colors, etc. The players, farnchise, and owner (Art Modell) moved to Baltimore. The name "Ravens" was chosen as the winner of a name the team contest, to pay homage to Edgar Allen Poe who was born in Baltimore. In 1999 the NFL awarded Cleveland an expansion team. That team assumed the name "Cleveland Browns" and continued play with all the team records and history of the franchise that moved to Baltimore.
The Baltimore Ravens were made when the Cleveland Browns decided to relocate to Baltimore. Baltimore had been upset that the Baltimore Colts had relocated to Indianapolis, and kept their team name and colors. So when Cleveland moved to Baltimore, they started new traditions with a new team name and uniforms. This allowed Cleveland to keep their team name and colors, when they eventually got a team again.
During the 1995 NFL season, Cleveland Browns owner Art Modell announced his intention to move the team to Baltimore for financial reasons. The team began playing as the Baltimore Ravens during the 1996 regular season. The NFL made arrangements to bring another team to Cleveland, starting with the 1999 season. The Browns' history, records and uniform colors were held over for the new Cleveland franchise.
Ted Marchibroda was the head coach of the Cleveland Browns in 1995 when owner Art Modell announced that he would be relocating the franchise to Baltimore to become the new Baltimore Ravens for the 1996 season.

He led the Ravens to their first Super Bowl victory (Super Bowl XXXV) just 2 years later.
Art Modell is most known for owning 2 NFL franchises. These were the Cleveland Browns which he owned from 1961-1995 and then the Baltimore Ravens from 1996-2004. He died in September 2012, aged 87.
