Perkembangan Perkebunan di Aceh Abad Ke XIII – XIX

Aceh has a strategic geographical expanse because it has a port port that was often visited by traders from other nations before the arrival of Islam until the arrival of colonialism. Aceh has relations with other nations because it has several commodities that are in demand by traders from outside the Aceh region. Commodities of the Acehnese people in the pre-Islamic period and the Islamic kingdom (pre-colonial) were the result of plantations. One of the main commodities is Pepper. This study uses historical methods and discourse data analysis. The historical method has several stages, namely heuristics, source criticism, interpretation, and historiography. The purpose of this study was to determine the spice trade, especially pepper, the influence of plantation development on multicultural communities in Aceh from the pre-colonial 13th century to the 19th century. As a trading center, the lives of Acehnese people depended on the results of trade from and inland areas. Goods originating from the interior are transported by boats to the coastal areas and from there they are transported abroad or traded to foreign traders who come there.Aceh memiliki hamparan geografis yang strategi karena memiliki Bandar pelabuhan yang sering dikunjungi para pedagang dari bangsa lain sebelum masuknya islam sampai kedatangan kolonial.  Aceh melakukan relasi dengan bangsa lain karena mempunyai beberapa komoditas yang diminati oleh para pedagang dari luar wilayah Aceh, Komoditas masyarakat Aceh pada masa pra islam dan masa kerajaan Islam (prakolonial )  adalah hasil dari perkebunan.  Salah satu komoditas utamanya adalah Lada. Penelitian ini menggunakan metode sejarah dan analisis data wacana.  Metode Sejarah  memiliki beberapa tahapan yaitu heuristik, kritik sumber, interpretasi, dan historiografi. Tujuan penelitian ini untuk mengetahui perdagangan rempah-rempah terutama lada pengaruh perkembangan perkebunan terhadap masyarakat multikultural di Aceh dari Pra kolonial abad ke 13 sampai abad ke 19. Sebagai pusat perdagangan, kehidupan orang Aceh tergantung dari hasil perdagangan dari dan daerah pedalaman.  Barang-barang yang berasal dari pedalaman diangkat dengan perahu-perahu ke daerah pesisir dan dari sana baru diangkut ke Luar Negeri atau diperdagangkan kepada pedagang-pedagang asing yang datang ke sana
