Passage: In 1895, members of the Gloucestershire Engineer Volunteers reenacted their famous stand at Rorke's Drift, 18 years earlier. 25 British soldiers beat back the attack of 75 Zulus at the Grand Military Fete at the Cheltenham Winter Gardens. Veterans of the American Civil War recreated battles as a way to remember their fallen comrades and to teach others what the war was all about. The Great Reunion of 1913, celebrating the 50th anniversary of the Battle of Gettysburg, was attended by more than 50,000 Union and Confederate veterans, and included reenactments of elements of the battle, including Pickett's Charge. During the early twentieth century, historical reenactment became very popular in Russia with reenactments of the Siege of Sevastopol  , the Battle of Borodino  in St Petersburg and the Taking of Azov  in Voronezh in 1918. In 1920, there was a reenactment of the 1917 Storming of the Winter Palace on the third anniversary of the event. This reenactment inspired the scenes in Sergei Eisenstein's film October: Ten Days That Shook the World. Large scale reenactments began to be regularly held at the Royal Tournament, Aldershot Tattoo in the 1920s and 30s. A spectacular recreation of the Siege of Namur, an important military engagement of the Nine Years' War, was staged in 1934 as part of 6-day long show. In America, modern reenacting is thought to have begun during the 1961-1965 Civil War Centennial commemorations. After more than 6,000 reenactors participated in a 125th anniversary event near the original Manassas battlefield, reenacting grew in popularity during the late 1980s and 1990s, and there are today over a hundred Civil War reenactments held each year throughout the country.

question:
Passage: Ferdinand died in January 1516 and was succeeded by his mentally unstable daughter Joanna. Within a few weeks, her son proclaimed himself her co-ruler as King Charles I of Castile and Aragon. Charles had been raised in Netherlands and his affairs were mostly controlled by the Flemish noble William de Croÿ, sieur de Chièvres.  In 1517, the seventeen-year-old King sailed to Castile, where he was formally recognised as King of Castile.  There, his Flemish court provoked much scandal, as de Croÿ shamelessly sold government privileges for personal money and installed other Flemish nobles into government offices.  In May 1518, Charles traveled to Barcelona in Aragon, where he would remain for nearly two years. Here, he haggled with Aragon's slightly stronger cortes, the Generalitat, for privileges and his formal recognition as King of Aragon. Aragon managed to maintain more local control than Castile did, but mostly because Aragon was poorer and there was no point in pressing the issue for extra tax money that wasn't there to be collected. In 1519, the King's paternal grandfather, Holy Roman Emperor Maximilian I, died.  Charles competed with King Francis I of France to win the imperial election by aggressively bribing prince-electors.  Charles won, becoming Emperor Charles V. He left Aragon to return to Castile to raise funds to pay down the debts he had incurred in the election.  The taxes granted to Charles at a Castilian cortes in Corunna would help spark the Revolt of the Comuneros of Castile.  Of more importance for Aragon, in the summer of 1519 Charles granted his permission to the Germanies to arm themselves against the raiding Muslim fleets. While permission had previously been granted under Ferdinand, Charles was able to force the Valencian nobles to accept this decision.
Question: How many years was it between when Ferdinand died and when Maximilian I died?
answer:

number
