Passages:
After centuries of Danish, Swedish and German rule the native Estonians started to yearn for independence during the period of national awakening while being governed by the Russian Empire. Established on 24 February 1918, the Republic of Estonia came into existence towards the end of World War I. During World War II, Estonia was then occupied by the Soviet Union in 1940, then Nazi Germany a year later and again in 1944 establishing the Estonian Soviet Socialist Republic. In 1988, during the Singing Revolution, the Estonian SSR issued the Estonian Sovereignty Declaration to defy against the illegal Soviet rule. Estonia then restored its independence during the 1991 coup by the Soviets on the night of 20 August 1991. The Franco-Prussian War or Franco-German War (German: Deutsch-Französischer Krieg, lit. German-French War, French: Guerre franco-allemande, lit. Franco-German War), often referred to in France as the War of 1870 (19 July 1870 – 10 May 1871), was a conflict between the Second French Empire and the German states of the North German Confederation led by the Kingdom of Prussia. The conflict was caused by Prussian ambitions to extend German unification. Some historians argue that the Prussian chancellor Otto von Bismarck planned to provoke a French attack in order to draw the southern German states—Baden, Württemberg, Bavaria and Hesse-Darmstadt—into an alliance with the North German Confederation dominated by Prussia, while others contend that Bismarck did not plan anything and merely exploited the circumstances as they unfolded. Poland's nobility were also more numerous than those of all other European countries, constituting some 10–12% of the total population of historic Polish–Lithuanian Commonwealth also some 10–12% among ethnic Poles on ethnic Polish lands (part of Commonwealth), but up to 25% of all Poles worldwide (szlachta could dispose more of resources to travels and/or conquering), while in some poorer regions (e.g., Mazowsze, the area centred on Warsaw) nearly 30%. However, according to  szlachta comprised around 8% of the total population in 1791 (up from 6.6% in the 16th century), and no more than 16% of the Roman Catholic (mostly ethnically Polish) population. It should be noted, though, that Polish szlachta usually incorporated most local nobility from the areas that were absorbed by Poland–Lithuania (Ruthenian boyars, Livonian nobles, etc.) By contrast, the nobilities of other European countries, except for Spain, amounted to a mere 1–3%, however the era of sovereign rules of Polish nobility ended earlier than in other countries (excluding France) yet in 1795 (see: Partitions of Poland), since then their legitimation and future fate depended on legislature and procedures of Russian Empire, Kingdom of Prussia or Habsburg Monarchy. Gradually their privileges were under further limitations to be completely dissolved by March Constitution of Poland in 1921.
