In 1921, whose funeral procession was the last public demonstration of anarchists in Soviet Russia allowed by the Bolshevik regime?

After a year of living in Moscow, Kropotkin moved to the city of Dmitrov in May 1918,[49] where he died of pneumonia on 8 February 1921. He was buried at the Novodevichy Cemetery in Moscow. Thousands of people marched in his funeral procession, including, with Vladimir Lenin's approval,[50] anarchists carrying banners with anti-Bolshevik slogans.[51] The occasion, the last public demonstration of anarchists in Soviet Russia, saw engaged speeches by Emma Goldman and Aron Baron.
