Friedrich Engels (1820-1895) was a German philosopher, social scientist, and influential figure within the communist movement. Along with Karl Marx, Engels is widely regarded as one of the founding fathers of modern communism. Engles was also a prolific writer and editor and is most well known for co-authoring The Communist Manifesto with Marx in 1848. Following Marx's death in 1883, Engles edited and published the second and third volumes of Das Kapital, Marx's seminal work on economic theory.

Engles was born in Germany in 1820, the son of a wealthy textile manufacturer. Early in his career, he pursued a degree in law, but soon discovered his passion for social and economic theory. Through his intellectual and economic connections, he became closely acquainted with Marx, who ultimately became his lifelong collaborator.

Engles admired Marx's radical views and the two quickly became close friends and allies. Together they set out to create a philosophical, economic and political system to embody their ideals and bridge the gap between their society's rich and poor. Their theories were highly controversial and criticized by many, but Engels and Marx persevered and their manifesto provoked insurrection throughout Europe. The two were actively involved in all aspects of the communist movement, and their writings remain extremely influential in radical thought today.

Engels' work was highly influential in a variety of fields, and he was credited with the building the foundations of the modern communist movement. After Marx's death, he continued to fight for the cause, editing and publishing Das Kapital. He also wrote under the pseudonym of Friedrich Oswald. Engels died in 1895, but his legacy lives on in his written works, which continue to be studying and debated today. He also contributed to society by advocating for the rights of the working class, noting the extreme injustice that had been inflicted upon them in favor of the wealthy and powerful. Despite his controversial ideas,Engels is highly regarded and respected as a true revolutionary.
