The Flag of Berlin, Germany, is a distinctive bicolor flag consisting of two equal vertical bands of coal black (to the hoist side) and brick red (to the fly side). It was officially adopted on February 16, 2004. The flag represents the federal state of Berlin within the Federal Republic of Germany. The colors are symbolic, with black often associated with the city’s turbulent past under Prussian rule and red representing the communist regime during the division of Germany. It’s important to note that this design is unique to Berlin, as other German states have different flag designs. The flag serves as a visible symbol of Berlin’s identity within the broader context of the nation.
