What was the difference between North and South Vietnam during the war?

Why was there conflict between North and South Vietnam?

The land was split. A scar drawn across the map at the 17th parallel, but the wound was deeper, felt in the villages, in the blood. A single country with two souls, pulling apart. The air itself felt heavy with waiting.

In the North, there was one name, a single current pulling everyone: Ho Chi Minh. He was the promise of reunification, of a land for its own people, under a single red banner. This idea, it was a fever. To make the country whole again, to erase that scar.

Down South, the heart was fractured. Ngo Dinh Diem ruled, but he did not reign in the peoples hearts. His face was a stranger's. My grandmother, who lived in Saigon her whole life, she never accepted him. So many southerners looked to the North, to Ho, as the true soul of Vietnam.

The fighting did not start like a storm. It was a slow poison, seeping into the earth. From 1958, it came from within the South itself. Neighbors, farmers, people you knew, rising in the night. The Viet Cong. A ghost army born from dissent, nurtured by the North. A brothers war.

• Ideological Chasm: The fundamental conflict was between two worlds. The Democratic Republic of Vietnam (North Vietnam) was a communist state seeking national reunification. The Republic of Vietnam (South Vietnam) was a staunchly anti-communist, capitalist state backed by the United States.

• Failure of the Geneva Accords: The 1954 Geneva Accords ended the First Indochina War and temporarily divided Vietnam. The plan was for a nationwide election in 1956 to unify the country. Ngo Dinh Diem, fearing a landslide victory for the popular Ho Chi Minh, refused to participate, making the division permanent and war inevitable.

• Diem's Unpopular Rule: Diem’s regime was corrupt and repressive. He favored the Catholic minority, alienating the vast Buddhist majority. His brutal crackdowns on all political opposition and failed land reforms created widespread resentment among the rural population, which was the backbone of the country.

• The Southern Insurgency: The National Liberation Front (NLF), known as the Viet Cong, was established in South Vietnam in 1960. It was a southern resistance movement, directed and supplied by Hanoi, that waged a relentless guerrilla war against Diem's government (the ARVN) and its American advisors. My uncle fought for the ARVN near Quang Tri; he said you never knew who the enemy was.
