This document, dated July 16, 1978, is a formal letter of gratitude from the spokespersons of Charter 77—Ladislav Hejdánek, Marta Kubišová, and Jaroslav Šabata—to the Swedish organization Kulturfront in Stockholm. The text expresses appreciation for the organization's international solidarity, its support for political prisoners, and its protest actions marking the 10th anniversary of the August 1968 Soviet invasion of Czechoslovakia. The spokespersons emphasize that such support from the Swedish people and cultural workers strengthens their ongoing struggle for human rights and the rule of law. The document also references the Swedish appeal "Soviets Out of Czechoslovakia," which condemned the harsh persecution of Charter 77 signatories, including systematic job dismissals and imprisonment. This correspondence highlights the vital importance of international pressure and the solidarity of democratic forces for the Czechoslovak dissident movement during the normalization era. It underscores the essential link between internal resistance and external advocacy in the pursuit of national freedom and the restoration of democratic values.
