Citizenship is the state of being a citizen of a particular social, political, national, or human resource community. The term describing all citizens as a whole is citizenry.

In law, citizenship denotes a link between an individual and a state. Under international law, citizenship is synonymous to nationality, although the two may have different meanings under national law. A person who does not have citizenship in any state is stateless.

Generally citizenship is seen as the relation between an individual and a particular nation. For example, a person can be described as being a citizen of Australia or Egypt or Ireland. While in ancient Greece the main political entity was the city-state, during the past five hundred years with the rise of the nation-state, citizenship is most closely identified with being a member of a particular nation. To some extent, certain entities cross national boundaries such as trade organizations, non-governmental organizations as well as multi-national corporations, and sometimes the term "citizen of the world" has been applied in the sense of people having less ties to a particular nation and more of a sense of belonging to the world in general, but generally citizenship is seen as a marker denoting membership in a nation.

Dirk Werner Nowitzki (German pronunciation: [ˈdɪʁk ˈvɛʁnɐ noˈvɪtski]) (born June 19, 1978) is a German professional basketball player who plays for the Dallas Mavericks of the National Basketball Association (NBA). An alumnus of Röntgen Gymnasium and DJK Würzburg basketball club, Nowitzki was drafted ninth overall by the Milwaukee Bucks in the 1998 NBA Draft, and was immediately traded to the Mavericks, where he has played ever since. Standing 7 ft 0 in (2.13 m), Nowitzki plays the power forward position but also has the athleticism and shooting ability to play the other frontcourt positions, center and small forward.

Nowitzki has led the Mavericks to 12 consecutive NBA Playoffs (2000–01–2011–12), including an NBA Finals appearance in 2006 and the franchise's first championship in 2011, making him one of only 5 players in NBA history to win a championship while being the only NBA All-Star on the team. He is an 11-time All-Star and 12-time member of the All-NBA Teams, and the first European-born player in NBA history to receive the NBA Most Valuable Player Award. He is the first Maverick ever to be voted into an All-NBA Team and also holds several all-time Mavericks franchise records. Only Nowitzki and three other players have ever averaged more than 25 points and 10 rebounds in the NBA playoffs, and only Nowitzki and Kareem Abdul-Jabbar have managed 4 consecutive 30-point, 15-rebound games in the playoffs. Additionally, Nowitzki is the only player in NBA history to get 100 blocks and 150 3-pointers in a single season.
