An archaeological study on the Daegaya region together with the Geumgwan Gaya region in Gimhae is a critical part of the archaeological research into the Gaya region. Studies have been conducted with focus on a large variety relics excavated from stone lined tombs and their surrounding remains. On the contrary, there have been relatively few studies on stone chamber tombs that well reflect the fast-changing society at the time as part of the radical changes in funeral and burial customs introduced and settled in around the 6th century.
 Notwithstanding it, several studies were conducted but left something to be desired due to the lack of examination into a number of topics, including the concrete background of introduction of Baekje style stone chamber tombs and their dissipation, localities and local differences between Goryeong and Hapcheon regions that served as a heartland to Daegaya, introduction of stone chamber tombs with horizontal entrance and their evolvement, introduction of Silla-style stone chamber tombs after the collapse of Gaya, preservation of local tradition seen during the process of gaining popularity and the introduction of new building techniques.
 Against this backdrop, this study has made new attempts of classification and stage settings for stone chamber tombs in the Daegaya region as part of the effort to properly address the issues described above, based on which I have sought to revive the overall development of stone chamber tombs identified in the Daegaya region and their historical significance in consideration of relevant historical implications. 
 A variety of stone chamber tombs in Goryeong and Hapcheon regions that served as a heartland to Daegaya have been classified into a number of categories with walk-in stone chamber tombs and horizontally-prepared stone chamber tombs classified into 12 and 13 categories, respectively, which in turn were set to different stages, depending on several different factors, including the form and stage of construction as well as structural characteristics such as temporal and spatial variation, different styles and shapes of entrance, and the shape of plane surface of the burial chamber to examine the architectural and historical implications in each stage. 
 First of all, the period of building walk-in and the horizontally-prepared stone chamber tombs can be classified into four different stages: the second quarter of the 6th century, third quarter of the 6th century, fourth quarter of the 6th century and the 7th century and afterwards, which are also named the period of introduction, expansion, prevalence and decline.
 The period of introduction, or Stage 1, saw a distinct difference in structure of tombs between Goryeong and Hapcheon although the both belong to the same Daegaya. That is, Goryeong adopted horizontally-prepared stone chamber tombs under the influence of Baekje while Hapcheon chose Silla style walk-in stone chamber tombs. This noticeable difference in the form of tombs is assumed to reflect historical backgrounds at the time characterized by close kinships between Daegaya’s ruling class and Baekje that resulted in building horizontally-prepared stone chamber tombs in Goryeong and the matrimonial alliance between Daraguk as a part of Daegaya Confederation and Silla that explains the Silla style walk-in stone chamber tombs and relics found in Hapcheon. 
 The period of expansion, or Stage 2, features expansion of Baekje style horizontally-prepared stone chamber tombs that originated from the Goryeong region to the Hapcheon region and adoption of Baekje style walk-in stone chamber tombs even among general public. These Baekje style walk-in stone chamber tombs used coffins, which indicates sustained affinity toward the Baekje region and contained the Okjeon style iron-plate ritual utensil with bird decorations that demonstrates the preservation of regional tradition. This is also the period when stone chamber tombs with a variety of forms were built by accepting changes from the previous periods over time and adopting new factors attained from the outside while preserving the tradition of stone chamber tombs in previous periods. 
 However, this period also saw huge historical changes in and around the Gaya region, which were incorporated into building stone chamber tombs. That is, in the third quarter of the 6th century, or the beginning part of this period, Daegaya and Gaya in the western Gyeongnam region were destroyed by Silla marching west.
 The period of prevalence, or Stage 3, saw the demise of Baekje style stone chamber tombs that were found in the period of introduction in the Daegaya region and a sharp rise of Silla stone chamber tombs even among general public, and in the fourth quarter of the 6th century with a little bit of influence of Daegaya left, Silla enforced its local system with focus on Daeyaju established in 565 in the Goryeong region where Daegaya collapsed but this was a chaotic period marred by severe conflicts and clashes between Silla and Baekje as indicated by the Daeyaseong battle that occurred in 642.
 Under these circumstances, stone chamber tombs built in the Daegaya region were mostly influenced by Silla.
 The period of decline is characterized by a noticeable decrease in the number of stone chamber tombs and their size also shrunk, resulting in the prevalence of small stone chamber tombs. And the existing graveyard sites gave way to new graveyard sites. These disruptive changes that included the establishment of new graveyard along with the standardization and reduction of stone chamber tombs in terms of structure and scale are presumably due to the regulations by Silla’s ruling class on burial customs upon establishment of control over major regions throughout the country.
 During the period of introduction through prevalence, most traditional items typically found in burial chambers in Okjeon graveyard sites, including wooden cover, iron-plate ritual utensil with bird decorations, coffin nails, coffin hooks, metal fittings for coffins, and other tomb related structure went out of sight, presumably walking on the path to demise, and stone chamber tombs started to get unified and standardized under the influence of Silla.
