Question: Who is currently in charge of the city where Desiderius was born?

full_context: Document 1: Anna d'Este: Anna d'Este was born on 16 November 1531, the eldest daughter of the Duke of Ferrara Ercole II (son of Lucrezia Borgia and grandson of Pope Alexander VI) and his wife, Renée of France (daughter of King Louis XII of France). She grew up in Ferrara, where she received an excellent education. The future writer and scholar Olympia Fulvia Morata was chosen as one of her companions at court.
Document 2: Boppard: The mayor is elected every eight years. Boppard's current mayor, elected on 1 August 1997 and again on 10 April 2005, is Dr. Walter Bersch (born 1954), and his deputies are Dr. Heinz Bengart, Ruth Schneider and Horst-Peter Hassbach.
Document 3: Munich: Munich's current mayor is Dieter Reiter of the Social Democratic Party of Germany. Munich has been governed by the SPD for all but six years since 1948. This is atypical because Bavaria – and particularly southern Bavaria – has long been identified with conservative politics, with the Christian Social Union gaining absolute majorities among the Bavarian electorate in many elections at the communal, state, and federal levels, and leading the Bavarian state government for all but three years since 1946. Bavaria's second most populous city, Nuremberg, is also one of the very few Bavarian cities governed by an SPD-led coalition.

Document 5: Auckland: In October 2010, Manukau City mayor Len Brown was elected mayor of the amalgamated Auckland Council. He was re-elected for a second term in October 2013. Brown did not stand for re-election in the 2016 mayoral election, and was succeeded by successful candidate Phil Goff in October 2016. Twenty councillors make up the remainder of the Auckland Council governing body, elected from thirteen electoral wards.
Document 6: Roman mythology: The Aeneid and Livy's early history are the best extant sources for Rome's founding myths. Material from Greek heroic legend was grafted onto this native stock at an early date. The Trojan prince Aeneas was cast as husband of Lavinia, daughter of King Latinus, patronymical ancestor of the Latini, and therefore through a convoluted revisionist genealogy as forebear of Romulus and Remus. By extension, the Trojans were adopted as the mythical ancestors of the Roman people.

He united much of Europe during the early Middle Ages. He was the first recognised emperor in western Europe since the fall of the Western Roman Empire three centuries earlier. The expanded Frankish state that Charlemagne founded is called the Carolingian Empire.

Document 10: Ljubljana: Between 2002 and 2006, Danica Simšič was mayor of the municipality. Since the municipal elections of 22 October 2006 until his confirmation as a deputy in the National Assembly of Slovenian in December 2011, Zoran Janković, previously the managing director of the Mercator retail chain, was the mayor of Ljubljana. In 2006, he won 62.99% of the popular vote. On 10 October 2010, Janković was re-elected for another four-year term with 64.79% of the vote. From 2006 until October 2010, the majority on the city council (the Zoran Janković List) held 23 of 45 seats. On 10 October 2010, Janković's list won 25 out of 45 seats in the city council. From December 2011 onwards, when Janković's list won the early parliamentary election, the deputy mayor Aleš Čerin was decided by him to lead the municipality. Čerin did not hold the post of mayor. After Janković had failed to be elected as the Prime Minister in the National Assembly, he participated at the mayoral by-election on 25 March 2012 and was elected for the third time with 61% of the vote. He retook the leadership of the city council on 11 April 2012.

Document 12: Ansa, Queen of the Lombards: Ansa or Ansia (died after 774) belonged to an aristocratic family of Brescia and was the wife of Desiderius (756-774), King of the Lombards. The Latin name does not imply a Romano-Italic origin, as Romans and Lombards in the eighth century tended to take either German or Latin names. She was probably a Lombard, the daughter of Verissimo and sister of King Hildeprand, Arechis, and Donnolo, and niece of King Liutprand.
Document 13: Aistulf: Aistulf (also Ahistulf, Aistulfus, Haistulfus etc.; ; died December 756) was the Duke of Friuli from 744, King of Lombards from 749, and Duke of Spoleto from 751.

Document 15: Fastrada: Fastrada became the third wife of Charlemagne, marrying him in October 783 at Worms, Germany, a few months after Queen Hildegard’s death. A probable reason behind the marriage was to solidify a Frankish alliance east of the Rhine when Charles was still fighting the Saxons.
