The surname DEC is believed to have originated in Poland, where it is thought to have derived from the Polish word "dec" meaning "breath" or "breeze." The earliest records of the name date back to the 16th century, with references found in historical documents from the region.
One of the earliest known bearers of the DEC surname was Jan DEC, a Polish nobleman who lived in the late 1500s. He was a prominent figure in the court of King Sigismund III Vasa and played a significant role in the Polish-Swedish war of the early 17th century.
In the 17th century, the DEC name also appears in various records from the town of Krakow, where it is believed that a branch of the family had settled. One notable individual from this time was Tomasz DEC (1620-1689), a respected scholar and professor of philosophy at the Jagiellonian University.
As the DEC family spread throughout Poland, variations in the spelling of the name began to emerge, with forms such as "Dets" and "Detz" appearing in some historical documents. This was likely due to regional dialects and the inconsistencies in record-keeping during that era.
The DEC surname eventually made its way beyond Poland's borders, with records indicating that members of the family migrated to other parts of Europe, including Germany and Russia. One notable figure from this period was Mikhail DEC (1748-1823), a Russian military officer who served under Catherine the Great and played a significant role in the Russo-Turkish War of 1787-1792.
Another prominent individual bearing the DEC surname was Stanisław DEC (1876-1939), a Polish politician and diplomat who served as the Minister of Foreign Affairs for Poland in the 1920s. He played a crucial role in shaping Poland's foreign policy during the interwar period.
