The German navies—specifically the , , and —built a series of light cruisers between the 1890s and 1940s. The authorization for a major construction program for light cruisers came in the 1898 Naval Law, which ordered the acquisition of thirty vessels of the type. The first such class of light cruiser, the , was based on several intermediate designs of unprotected cruisers, such as the , and avisos—dispatch boats—like . The ten members of the class set the basic parameters for all later light cruisers of the . Over the following two decades, the Germans built a further thirty-seven light cruisers; these vessels slowly grew in size, speed, armament, and armor. The original SK L/40 gun was replaced by the more advanced L/45 model in the , and it was in turn superseded by the more powerful SK L/45 gun in the . A waterline armored belt was introduced in the , which significantly improved the ships' defensive qualities.

These forty-seven cruisers all saw action across the globe in World War I; the bulk served with the German fleets in the North and Baltic Seas, though several served on foreign stations, typically as commerce raiders. Sixteen cruisers were lost during the war to causes ranging from enemy submarines and naval mines to combat with hostile cruiser squadrons. Most of the survivors were either scuttled in Scapa Flow in June 1919 or seized by the various Allied governments as war prizes following Germany's defeat. Several of these were commissioned into their fleets: Italy received three cruisers and France took four. Germany was permitted to retain eight of the oldest cruisers; of these, five continued to serve in secondary roles into World War II.

The Treaty of Versailles allowed Germany to replace these old cruisers, and the first such new vessel, , was built in the early 1920s to a design based on the last wartime classes. A new approach was taken in the five members of the succeeding and es with triple gun turrets and hybrid diesel/turbine propulsion systems. A further six ships of the were planned in the late 1930s, but the outbreak of war forced their cancellation. The six cruisers of the , , and classes all served in World War II, and only one——survived the war intact. Two were sunk during the invasion of Norway and the remaining three vessels were destroyed by Allied bombers in the final months of the war. , the last cruiser completed by Germany, was seized by the Soviet Union and commissioned as , serving until the late 1950s.

Gazelle class

The class was the first modern light cruiser design of the Imperial Navy. This new class of ships was the culmination of earlier unprotected cruisers—the —and several experimental intermediate types, such as and . The Germans intended to use the s both as fleet scouts and overseas cruisers. Though they were smaller than their foreign contemporaries, they were strongly built and powerfully armed ships for the period. As a result, they could effectively perform the two roles envisioned for the design. According to the historian Eric Osborne, "[t]he light cruisers of the -class established a trend for future ships of this general design ... [they] carried little or no armor, the chief asset being speed." Indeed, all future light cruisers built by the Imperial Navy generally followed the same pattern, with few fundamental changes.

The ten ships served in a variety of roles throughout their career. Before the war, most served on foreign stations or with the main fleet, while and served as training ships. Due to their age, the had been placed in reserve by 1914, but after the outbreak of World War I in August 1914, they were mobilized for active service. Most were initially used as coastal defense vessels in the Baltic, but and remained in service with the fleet. was sunk by several British battlecruisers at the Battle of Heligoland Bight on 28 August 1914. was torpedoed and sunk by at the Battle of Jutland on 31 May 1916 with the loss of almost her entire crew. In the Baltic, was torpedoed and sunk by the British submarine on 7 November 1915.

The seven surviving ships were withdrawn from front-line service in 1916 and used for auxiliary purposes. They went on to serve in the new , with the exception of , which was broken up for scrap in 1920. was sold to Yugoslavia in 1925 and renamed , while and were scrapped in the early 1930s. , , and were used as barracks hulks for the rest of the 1930s. After the outbreak of World War II, and were converted into floating anti-aircraft batteries and defended German ports from 1940 to the end of the war, when they were scuttled by their crews on 3 May 1945. meanwhile remained in service as a barracks ship through the end of the war. eventually returned to German control in 1943, and she was destroyed in December of that year by British Motor Torpedo Boats.

Bremen class

The class was an incremental improvement over the earlier s, being larger and slightly faster. They were otherwise very similar, and mounted the same main battery of 10.5 cm guns. One ship, , was fitted with new Parsons steam turbines to evaluate their use in future designs; the other vessels retained proven triple-expansion engines. The ships' peacetime careers saw them serving in several capacities. and served in the East Asia Squadron early in their careers; the other ships, save , were assigned to the fleet scouting forces. was used as a torpedo training ship.

The ships saw extensive action during the war. fought with the East Asia Squadron at the Battle of Coronel and was sunk at the subsequent Battle of the Falkland Islands in late 1914. was moderately damaged at Jutland, and , , and engaged Russian forces at the Battle of the Gulf of Riga and during Operation Albion in 1915 and 1917, respectively. and were withdrawn from service in 1916, the latter after being badly damaged by a mine. Only and were retained after the war; the other surviving ships were seized by Britain as war prizes and scrapped in the early 1920s. Both were used as training cruisers in the 1920s and then as barracks ships from the 1930s. was sunk by British bombers in 1944 during World War II, and was loaded with chemical weapons and scuttled in the Skaggerak in 1947 to dispose of the munitions.

Königsberg class (1905)

The class continued the general trend of slightly larger and faster German light cruiser designs. Like the s, one member of the new class——was equipped with turbines for testing purposes. They retained the same armament and armor protection of the class. All four ships were employed with the High Seas Fleet after they were commissioned, though was deployed to Asia in 1910, and was sent to East African waters in 1914.

All four ships saw major action during the war. , based in Dar es Salaam at the outbreak of war, began a short and unsuccessful commerce raiding career in the region, though she did destroy the British cruiser . She eventually became trapped in the Rufiji River and was later destroyed by a pair of British monitors in 1915. The war was not over for the vessel, however, as her guns were removed and used extensively in Paul von Lettow-Vorbeck's East African Campaign. participated in the battles at Coronel and the Falkland Islands, where she was sunk. saw action at the Battle of Heligoland Bight in August 1914. Both she and also participated in the Battle of Jutland. was used as a training ship after 1917, and was converted into a seaplane tender in 1918. Both were seized by Britain as war prizes and scrapped in the early 1920s.

Dresden class

The two cruisers ordered in the 1905–1906 program represented a continuation in the slow, upward trend in displacement, though the two ships had the same top speed as the earlier -class ships. Like the preceding classes, one ship was equipped with turbine engines, and one with reciprocating machinery; this was to be the last time a German cruiser utilized the older triple-expansion engines. All subsequent designs adopted steam turbines universally. and had very active and short careers. Both vessels served on foreign stations for the majority of their careers; was assigned to the East Asia Squadron after she entered service, and spent much time off the North American Atlantic coast.

initially operated as a commerce raider in the Atlantic after the outbreak of war in 1914, before steaming around South America to join von Spee's squadron as it approached the continent. She took part in the battles of Coronel and the Falkland Islands, and she was the only German cruiser to escape destruction at the latter. She was later trapped by British cruisers at Más a Tierra in March 1915. After a short bombardment from the British ships, s crew scuttled her in the harbor. , meanwhile, had been detached from the East Asia Squadron to act as an independent raider in the Indian Ocean. She had a successful career hunting Allied merchant ships in the area, and also sank the Russian protected cruiser in Penang harbor. Shortly thereafter, the Australian light cruiser caught off the Cocos Islands and inflicted serious damage, forcing her to beach on the island of North Keeling.

Kolberg class

The class represented the first major improvement in combat power for German light cruisers, both qualitatively and quantitatively. They were armed with the longer-barrel 10.5 cm SK L/45 gun, which had a higher muzzle velocity and thus greater range than the earlier L/40 weapon. In addition, they carried an extra pair of guns, which strengthened their broadside. This was on a displacement of over a thousand tons greater than the preceding class. All four ships were also powered by turbines, which granted them a significant increase in speed over the earlier vessels.
