The theme of conflict in Lord of the Flies is central to the novel, manifesting in various forms such as internal struggles, interpersonal clashes, and broader societal tensions. The story explores the conflict between civilization and savagery, the struggle for power, and the inherent evil within humanity. These conflicts drive the narrative and highlight the breakdown of order on the island.

Jack's internal conflict is a significant aspect of the novel. Initially, he struggles between maintaining civility and embracing savagery. His hesitation to kill a pig reflects this inner turmoil. However, Jack's desire to project strength and avoid humiliation leads him to embrace violence, both against animals and other boys. This shift highlights the conflict within Jack as he grapples with his identity and the allure of power.

The introduction of the parachutist in chapter six symbolizes the broader conflict of man versus man, both on the island and in the outside world. The dead parachutist, a casualty of war, represents the failure of adult civilization and the chaos beyond the island. The boys' misinterpretation of the parachutist as a "beast" amplifies their fear and accelerates their descent into savagery. This event underscores the conflict between rationality and fear, leading to the collapse of their fragile society.

The conflict between Piggy and Jack exemplifies the clash between civility and anarchy. Piggy, who relies on order and structure for survival, is constantly threatened by Jack's aggressive and authoritarian nature. When Jack leaves the group, Piggy feels liberated, able to express his ideas without fear. This dynamic illustrates the tension between democratic ideals, symbolized by the conch, and the destructive force of unchecked power.

Jack's rise to power on the island parallels the rise of fascism, drawing a connection to World War II and Hitler's dictatorship. The boys' need for protection and survival mirrors the desperation of pre-war Germany, leading them to follow Jack's authoritarian rule. This allegory highlights the dangers of totalitarianism and the conflict between democratic values and oppressive regimes.
