Lothar von Trotha: Architect of Colonial Extermination

Adrian Dietrich Lothar von Trotha was born in Magdeburg on July 3, 1848, and entered the Prussian Army in 1865. He served in the Austro-Prussian War of 1866 and Franco-Prussian War of 1870–1871 before becoming a specialist in colonial coercion.

As commander of the Schutztruppe in German East Africa from 1894 to 1897, Trotha suppressed African resistance. In 1900, he commanded the 1st East Asian Infantry Brigade in the international expedition dispatched against the Boxer movement in Qing China. Kaiser Wilhelm II appointed him commander of the Schutztruppe in German South West Africa on May 3, 1904; he arrived on June 11 and replaced Governor Theodor Leutwein as military commander.

Trotha was recalled in November 1905 and retired from active service in 1906. He died in Bonn on March 31, 1920, aged 71.

Trotha commanded an imperial army equipped with rifles, machine guns and artillery, supported by railways, telegraph lines, settler intelligence and Berlin’s finance. He rejected Leutwein’s preference for negotiated submission and treated the Herero population—not only armed combatants—as an enemy to be removed.

At Waterberg on August 11, 1904, approximately 4,000–6,000 German troops attempted to encircle the main Herero concentration. The incomplete cordon left an eastern route toward the water-scarce Omaheke. German patrols then guarded water points and prevented refugees from returning. On October 2, 1904, Trotha issued his Vernichtungsbefehl, or extermination order.

“Within the German borders every Herero, with or without a rifle, with or without cattle, will be shot. I shall no longer accept women and children.” — Lothar von Trotha, 1904, Proclamation to the Herero People

Berlin rescinded the order on December 8, 1904, following objections that included political, missionary and economic concerns. The underlying violence continued through imprisonment, forced labor, malnutrition and disease. From 1905, surviving Herero and Nama were held in camps including Shark Island, Swakopmund and Lüderitz.

German colonial records counted about 80,000 Herero before the war and 15,130 afterward, implying the loss of roughly 64,870 people, or about 81%, by 1911. The 1918 British Report on the Natives of South-West Africa and Their Treatment by Germany, commonly called the Blue Book, used colonial evidence to document mass death, dispossession and abuse. Modern summaries frequently estimate 60,000–80,000 Herero deaths and about 10,000 Nama deaths during 1904–1908. Isabel V. Hull’s 2005 study reports that approximately 75%–80% of the Herero and around 50% of the Nama died; exact totals remain disputed because German records were incomplete and communities were dispersed.

“The Herero people must leave the country.” — Lothar von Trotha, 1904, Proclamation to the Herero People

The killings formed only part of the Herero and Nama genocide. German authorities confiscated land and livestock, prohibited independent African landholding and forced survivors into a controlled labor system. Prisoners were subjected to medical and racial research; human remains were sent to German institutions.

The chronology shows a shift from battlefield action to demographic destruction. Trotha’s October 1904 order gave explicit form to a policy already enacted after Waterberg; its December 1904 cancellation did not restore confiscated land, release prisoners or end the German Empire’s coercive labor regime.

Trotha defended his strategy as a necessary “race war.” In a letter dated October 4, 1904, he argued that the Herero nation had to be destroyed or expelled and claimed that accepting women and children would endanger German troops. He presented terror as deterrence and exterminatory expulsion as military necessity.

This defence collapses the distinction between fighters and civilians. Herero families at Waterberg included children, older people and noncombatants; Trotha’s proclamation expressly targeted people regardless of whether they carried weapons. His policy also continued after the principal Herero field force had been broken.

German officials did not speak with one voice. Chancellor Bernhard von Bülow sought cancellation of the extermination order, while missionaries and some colonial administrators condemned its consequences. Yet the imperial government financed the war, retained the colony, imprisoned survivors and preserved settler gains. By 1907, German military spending on the conflict had risen to roughly 585 million marks according to contemporary Reich budget accounting cited by historian Horst Drechsler. Institutional disagreement over method did not end colonial dispossession.

Trotha became a central figure in debates over German colonial genocide because his written order makes intent unusually explicit. The United Nations’ 1985 Whitaker Report identified the destruction of the Herero among genocides of the 20th century. In 2004, German Development Minister Heidemarie Wieczorek-Zeul apologized in Namibia and acknowledged German responsibility, 100 years after Waterberg.

In 2007, members of the von Trotha family traveled to Namibia and apologized to Herero representatives. Germany returned human remains in several ceremonies beginning in 2011. On May 28, 2021, Germany officially recognized the 1904–1908 killings as genocide and announced a €1.1 billion development program over 30 years; the agreement was negotiated with Namibia but rejected by major Herero and Nama representative bodies for excluding them from direct negotiations and for framing payment as development aid rather than legally enforceable reparations.

Trotha’s name remains attached to streets and military commemoration controversies in Germany. His importance is not that he acted alone: it is that he converted the German Empire’s racial hierarchy, settler demands and military capacity into an explicit program of expulsion and destruction.
