This article provides a critical examination of the substantial influence of Hegel's absolute idealism on Heidegger's ontology, exploring how this influence is simultaneously manifested and reconfigured. While Hegel, a representative of modernity, foregrounded concepts such as freedom, rationality, consciousness, and history; Heidegger, his modern critic, fundamentally reoriented philosophical inquiry towards Being and time. Based on the insights of prominent Heideggerian scholars—Gadamer, Haar, Janicaud, and Kolb—this study posits that Heidegger's foundational concepts, notably historicity and dialectic, bear clear Hegelian traces. The paper meticulously illustrates Heidegger's active efforts to redefine these inherited concepts in service of his distinctive philosophical enterprise. Furthermore, it delineates the intricate commonalities and points of departure between these two thinkers concerning pivotal domains like history, phenomenology, and modernity. The research ultimately concludes that although significant parallels between Hegel and Heidegger—particularly in the later Heidegger—suggest a neo-Hegelian current; Heidegger’s philosophy ultimately surpasses the Hegelian framework. This is most evident in his profound understanding of the origin and end of metaphysics, where he critically grapples with and seeks to move beyond Hegel's philosophical system.
