Gastroesophageal reflux occurs when the LES is weak or relaxes inappropriately, allowing the stomach's contents to flow up into the esophagus. The severity of GERD depends on LES dysfunction as well as the type and amount of fluid brought up from the stomach and the neutralizing effect of saliva.
Prussia, with its capital in KÃ¶nigsberg and from 1701 in Berlin, shaped the history of Germany. In 1871, German states united to create the German Empire under Prussian leadership. In November 1918, the monarchies were abolished and the nobility lost its political power during the German Revolution of 1918â19. The Kingdom of Prussia was thus abolished in favour of a republicâthe Free State of Prussia, a state of Germany from 1918 until 1933.
Prussia is considered the legal predecessor of the unified German Reich (1871â1945) and as such a direct ancestor of today's Federal Republic of Germany.
