Erling Persson founded Hennes (Swedish for "Hers") in 1947 in Vasteras, Sweden. The first store sold women's clothing at affordable prices, targeting the growing post-war Swedish middle class. Persson's concept was to offer fashionable clothing at prices accessible to ordinary consumers, a model that would later be described as fast fashion.
In 1968, Erling Persson acquired Mauritz Widforss, a hunting and fishing equipment retailer in Stockholm. The acquisition brought the Mauritz name into the company and expanded the product range to include menswear. The company was subsequently renamed Hennes & Mauritz, which was later shortened to H&M.
H&M expanded outside Sweden for the first time in 1964, opening a store in Norway. The company continued its Nordic expansion through the late 1960s and 1970s, entering Denmark and Switzerland. In 1976, H&M opened its first store in the United Kingdom, in London, marking the beginning of its Western European expansion.
The company listed on the Stockholm Stock Exchange in 1974, providing capital for continued expansion. Erling Persson's son, Stefan Persson, joined the company in 1972 and became managing director in 1982. Under Stefan Persson's leadership, H&M accelerated its international expansion significantly.
H&M entered the German market in 1980, which became one of its largest markets. The company expanded into the Netherlands, Belgium, Austria, and Luxembourg through the 1980s and 1990s. In 1998, H&M entered France, and in 2000, the company opened its first US store in New York City, marking its entry into the North American market.
In 2007, H&M launched COS (Collection of Style), a premium contemporary brand targeting consumers seeking more refined, minimalist design at prices above the H&M flagship. COS established H&M Group's multi-brand strategy, demonstrating that the group could operate distinct brands with different aesthetics and price points.
The group subsequently launched Weekday in 2002 (acquired from the founders), Monki in 2006 (acquired), & Other Stories in 2013, Arket in 2017, and Afound in 2018. Each brand was designed to address a specific consumer segment without cannibalizing the H&M flagship.
In 2021, H&M Group announced the appointment of Helena Helmersson as CEO, the first woman to lead the company. Helmersson had previously served as the group's Chief Operating Officer and Head of Sustainability. She resigned in January 2024 and was succeeded by Daniel Ervér, who had been CEO of the COS brand.
For the full year ending 30 November 2025, H&M Group reported net sales of approximately 234 billion Swedish kronor, with sales in local currencies increasing by 2% in the fourth quarter. The group operated approximately 4% fewer stores at the end of the period compared to the prior year, reflecting a continued rationalization of the store network in favor of larger, more productive locations and digital channels.
