Jackson, the first US diplomat accredited to Bulgaria, presented his credentials to Prince Ferdinand I. Bulgarian-American diplomatic relations had been established at legation level in 1901, and Jackson\u2019s accreditation gave them a formal representative shape in Sofia. At the time, Bulgaria was still a principality under Ottoman suzerainty, but it was steadily expanding its international contacts. The event shows how Bulgaria\u2019s diplomacy developed before the declaration of full independence in 1908. Relations with the United States later passed through interruptions during wartime and the Cold War, but this early step marked the beginning of an official diplomatic channel.<\/p>\n<h2><strong>September 19, 2006 \u2014 Siemens Opens Its First Manufacturing Plant in Bulgaria<\/strong><\/h2>\n<p>On this day in 2006, German engineering company Siemens inaugurated its first manufacturing plant in Bulgaria, located in Blagoevgrad. The opening came shortly before Bulgaria joined the European Union and reflected the country\u2019s growing integration into European industrial and investment networks. Foreign manufacturing projects were important for employment, technology transfer, supplier development, and the modernization of regional economies outside Sofia. The Siemens plant also symbolized investor confidence at a moment when Bulgaria was preparing for EU membership and presenting itself as a competitive production location. The event belongs to the economic history of the transition period, when foreign investment reshaped parts of Bulgarian industry.<\/p>\n<p>Explore more of Bulgaria\u2019s story on <strong><a href=\"https:\/\/bronicable.com\/en\/\">Bronicable<\/a><\/strong>, including our <strong><a href=\"https:\/\/bronicable.com\/en\/category\/from-above\/\">Bulgaria From Above<\/a><\/strong> series and our guides to <strong><a href=\"https:\/\/bronicable.com\/en\/category\/bulgaria\/\">the best of Bulgaria<\/a><\/strong>.<\/p>\n<p>Continue with <a href=\"https:\/\/bronicable.com\/en\/on-this-day-in-bulgaria\/on-this-day-in-bulgaria-september-18\/\">September 18<\/a> or <a href=\"https:\/\/bronicable.com\/en\/on-this-day-in-bulgaria\/on-this-day-in-bulgaria-september-20\/\">September 20<\/a>.
