Q: Question: How old was the Duke of Saxony when he appointed Adolf I to hold Holstein and Stormarn? Passage 1:The 1935 Anniversary show commemorated the 2nd anniversary of the Mexican professional wrestling company Empresa Mexicana de Lucha Libre (Spanish for "Mexican Wrestling Promotion"; EMLL) holding their first show on September 22, 1933 by promoter and founder Salvador Lutteroth. EMLL was rebranded early in 1992 to become Consejo Mundial de Lucha Libre ("World Wrestling Council"; CMLL) signal their departure from the National Wrestling Alliance. With the sales of the Jim Crockett Promotions to Ted Turner in 1988 EMLL became the oldest, still-operating wrestling promotion in the world. Over the years EMLL/CMLL has on occasion held multiple shows to celebrate their anniversary but since 1977 the company has only held one annual show, which is considered the biggest show of the year, CMLL's equivalent of WWE's WrestleMania or their Super Bowl event. CMLL has held their Anniversary show at Arena Mexico in Mexico City, Mexico since 1956, the year the building was completed, over time Arena Mexico earned the nickname "The Cathedral of Lucha Libre" due to it hosting most of EMLL/CMLL's major events since the building was completed. EMLL held their first anniversary show at Arena Modelo in 1933 and returned to that building in 1937 through 1943. From 1934 through 1936 EMLL rented Arena Nacional for their shows, but in 1944 they began holding their anniversary shows at Arena Coliseo, an arena they owned. From 1944 through 1955 EMLL held all their anniversary shows at Arena Coliseo. Traditionally EMLL/CMLL holds their major events on Friday Nights, replacing their regularly scheduled Super Viernes show.
Passage 2:He was appointed to hold as fiefs Holstein and Stormarn, including Hamburg, by Lothair, Duke of Saxony, in 1111. By this appointment Adolf became the leader of the defence of Germany against the Wagri. Allied with Henry, the prince of the Obotrites, he repeatedly waged war on Wagria and the Rugians. After Henry's death (1127), Adolf remained allied with his sons Canute and Sventepolk, but they were soon dead and Lothair, by then King of Germany, had made Canute Lavard, a Danish prince, Duke of Schleswig. Feeling his authority threatened by the Danish upstart, Adolf attacked his castle of Albergs, captured the garrison, and destroyed its defences. He left his counties intact to his second son, Adolf II, since his eldest, Hartung, had been killed in the Second Battle of Chlumec in 1126.
Passage 3:In 1797 with the Treaty of Campo Formio, the Republic of Venice, including Zadar, came under the Austrian crown. In 1806 it was briefly given to the Napoleonic Kingdom of Italy, until in 1809 it was added to the French Illyrian Provinces. In November 1813 an Austrian force blockaded the town with the assistance of two British Royal Navy frigates HMS Havannah and Weazle under the 3rd Earl of Cadogan. On 9 December the French garrison of Zadar capitulated, and by the end of the year all of Dalmatia was brought back under the control of the Austrian Empire. After the Congress of Vienna (1815) until 1918, the town (bilingual name Zara Zadar ) remained part of the Austrian monarchy (Austria side after the compromise of 1867), head of the district of the same name, one of the 13 Bezirkshauptmannschaften in Dalmatia. The Italian name was officially used before 1867. It remained also the capital of Dalmatia province (Kronland).
