Goring was born on 12 January 1893 at the Marienbad Sanatorium in Rosenheim, Bavaria. His father, Heinrich Ernst Goring (31 October 1839 - 7 December 1913), a former cavalry officer, had been the first Governor-General of the German protectorate of South-West Africa (modern-day Namibia). Heinrich had five children from a previous marriage. Goring was the fourth of five children by Heinrich's second wife, Franziska Tiefenbrunn (1859-15 July 1943), a Bavarian peasant.

Goring and other senior officers were concerned that Germany was not yet ready for war, but Hitler insisted on pushing ahead as soon as possible. The invasion of Poland, the opening action of World War II, began at dawn on 1 September 1939. Later in the day, speaking to the Reichstag, Hitler designated Goring as his successor as Fuhrer of all Germany, "If anything should befall me", with Hess as the second alternate. Big German victories followed one after the other in quick succession. With the help of the Luftwaffe, the Polish Air Force was defeated within a week. The Fallschirmjager seized vital airfields in Norway and captured Fort Eben-Emael in Belgium. Goring's Luftwaffe played critical roles in the Battles of the Netherlands, Belgium and France in May 1940.  After the Fall of France, Hitler awarded Goring the Grand Cross of the Iron Cross for his successful leadership. During the 1940 Field Marshal Ceremony, Hitler promoted Goring to the rank of Reichsmarschall des Grossdeutschen Reiches (Reich Marshal of the Greater German Reich), a special rank which made him senior to all field marshals in the military, including the Luftwaffe. As a result of his promotion, he was then the top ranking soldier of all Germany until the end of the war. Goring had already received the Knight's Cross of the Iron Cross on 30 September 1939 as Commander in Chief of the Luftwaffe.  The UK had declared war on Germany immediately after the invasion of Poland. In July 1940, Hitler began preparations for an invasion of Britain. As part of the plan, the Royal Air Force (RAF) had to be neutralized. Bombing raids commenced on British air installations and on cities and centres of industry. Goring had by then already announced in a radio speech, "If as much as a single enemy aircraft flies over German soil, my name is Meier!", something that would return to haunt him, when the RAF began bombing German cities on 11 May 1940. Though he was confident the Luftwaffe could defeat the RAF within days, Goring, like Admiral Erich Raeder, commander-in-chief of the Kriegsmarine (navy), was pessimistic about the chance of success of the planned invasion (codenamed Operation Sea Lion). Goring hoped that a victory in the air would be enough to force peace without an invasion. The campaign failed, and Sea Lion was postponed indefinitely on 17 September 1940. After their defeat in the Battle of Britain, the Luftwaffe attempted to defeat Britain via strategic bombing. On 12 October 1940 Hitler cancelled Sea Lion due to the onset of winter. By the end of the year, it was clear that British morale was not being shaken by the Blitz, though the bombings continued through May 1941.
