Question: When did the Emperor of the French rule, whose last victorious battle was also The Battle of Saint-Dizier?
Context: Monument of Sokołowo - a monument commemorating the victims of the Battle of Sokołowo on May 2, 1848 during the Greater Poland Uprising.  In the battle the forces of the Prussian led by Gen. A. Hirschfeld were against the Polish insurgents who were helped by local peasants and their leader was Ludwik Mierosławski.  The victorious battle more than 300 insurgents were killed.  This event also marks the Song of 1848.  The monument was built according to Cyprian Norwid's idea. The Battle of Saint-Dizier was a battle during the War of the Sixth Coalition, fought on 26 March 1814, and is notable as Napoleon's last victory before he abdicated. Mehmet Shpendi, also known as Sokol Shpendi (1851–1915), a nationalist figure and guerrilla fighter, was one of the leading commanders of the Albanian Revolt of 1910, 1911, 1912 against Ottoman Empire and struggle for liberty against Kingdom of Montenegro in 1915.  Born in the village of Shala Pecaj, Dukagjini, he represented the general uprising of the Malsia Highlands against the Ottoman Empire and the Montenegrin forces.  In 1883, in Cezme in Koplik, Mehmet Shpendi, in the name of Dukagjin, sided with Ded Gjo Luli in order to resist the commission of Xhibalit which was formed in 1856 with the purpose of tricking the Montenegrins.  In 1890 Mehmet Shpendi founded the "Shala Djelmnia", an Albanian patriotic organization.  In 1910 Mehmet Shpendi managed to gather 3000 highlanders to the battle of Qafe and Agri against the Ottoman general Dergut Pasha.  The Ottoman battalions numbered 20 and were supplied with artillery cannons and modern weapons.  The Ottomans were frightened by the fierce fighting of the Highlanders and they lost the battle.  In 1911, Ded Gjo Luli and Mehmet Shpendi rose the flag Albanian flag for the first time in 400 years in the victorious battle of Decic.  He is regarded as a local hero. In northern European and German historiography, the French period (French: "Période française" , German: "Franzosenzeit" , Dutch: "Franse tijd" , Luxembourgish: "Fransousenzäit" ) was a late 19th-century term for the era between 1794 and 1815, during which most of Northern Europe was directly under French rule or within the French sphere of influence.  It is often confused with Napoleon I's rule, although, in the states west of the river Rhine, it began with their occupation by troops of the French Revolutionary Army in 1794.  However, in some parts of Germany it lasted roughly from 1804 to 1813 or (used in a stricter sense) from the dissolution of the Holy Roman Empire in 1806 to the Battle of Leipzig in 1813. Maximilian (Spanish: "Maximiliano"; born "Ferdinand Maximilian Joseph"; 6 July 1832 – 19 June 1867) was the only monarch of the Second Mexican Empire.  He was a younger brother of the Austrian emperor Francis Joseph I.  After a distinguished career in the Austrian Navy, he accepted an offer by Napoleon III of France to rule Mexico.  France (along with the United Kingdom and Spain, who both withdrew the following year after negotiating agreements with Mexico's democratic government) had invaded Mexico in the winter of 1861, as part of the War of the French Intervention.  Seeking to legitimize French rule in the Americas, Napoleon III invited Maximilian to establish a new Mexican monarchy for him.  With the support of the French army, and a group of conservative Mexican monarchists hostile to the liberal administration of new Mexican President Benito Juárez, Maximilian traveled to Mexico.  Once there, he declared himself Emperor of Mexico on 10 April 1864. The city of Hamburg was one of the most powerful fortresses east of the Rhine.  After being freed from Napoleonic rule by advancing Cossacks and other following Coalition troops it was once more occupied by Marshal Davout's French XIII Corps on 28 May 1813, at the height of the German Campaign during the War of the Sixth Coalition from French rule and occupation.  Ordered to hold the city at all costs, Davout launched a characteristically energetic campaign against a similar numbered Army of the North made up of Prussian and other Coalition troops under the command of Count von Wallmoden-Gimborn, winning a number of minor engagements.  Neither force was decidedly superior and the war ground to a halt and resulted in a rather stable front line between Lübeck and Lauenburg and further south along the Elbe river, even after the end of the cease-fire of the summer 1813.  In October 1813 a French column's movement towards Dannenberg resulted in the only major engagement in the North of Germany, the Battle of the Göhrde.  The defeated French troops retreated back to Hamburg. The Battle of Abukir (or Aboukir or Abu Qir) was a battle in which Napoleon Bonaparte defeated Seid Mustafa Pasha's Ottoman army on July 25, 1799, during the French campaign in Egypt.  It is considered the first pitched battle with this name, as there already was a naval battle on August 1, 1798 (a second pitched battle followed on March 8, 1801).  No sooner had the French forces returned from a campaign to Syria, than the Ottoman forces were transported to Egypt by Sidney Smith's British fleet to put an end to French rule in Egypt. The Battle of Arcis-sur-Aube (20–21 March 1814) saw an Imperial French army under Napoleon face a much larger Allied army led by Karl Philipp, Prince of Schwarzenberg during the War of the Sixth Coalition.  On the second day of fighting, Emperor Napoleon suddenly realized the long odds against him and hurriedly ordered a retreat.  The French were able to disengage and withdraw to the north because of the hesitations of the Austrian Field Marshal Schwarzenberg.  This was Napoleon's penultimate battle before his abdication and exile to Elba, the last being the Battle of Saint-Dizier. Napoléon Bonaparte ( ; ] ; 15 August 1769 – 5 May 1821) was a French military and political leader who rose to prominence during the French Revolution and led several successful campaigns during the French Revolutionary Wars.  As Napoleon I, he was Emperor of the French from 1804 until 1814, and again briefly in 1815 (during the Hundred Days).  Napoleon dominated European and global affairs for more than a decade while leading France against a series of coalitions in the Napoleonic Wars.  He won most of these wars and the vast majority of his battles, building a large empire that ruled over continental Europe before its final collapse in 1815.  One of the greatest commanders in history, his wars and campaigns are studied at military schools worldwide.  Napoleon's political and cultural legacy has endured as one of the most celebrated and controversial leaders in human history. Kamichetty Venougopala Rao Naidu better known as "The Grand Old Man of Yanaon" was Mayor and MLA of Yanaon during French rule in first half of 20th century.  He was one of the two powerful political leaders in Yanam during French rule.  His opponent was Bezawada Bapa Naidou, the first mayor of Yanam.  After death of Bapa Naidou, he became Mayor of Yanam (Maire de Yanaon) and even his family became very dominant in Yanam politics for at least 50 years thence.
