The main purpose of this paper is searching for answers to the almost enthusiastic support of the Portuguese State for Turkey’s accession to the European Union. The diplomatic position of Portugal is intriguing since both states are historically unfamiliar one to another—not only for their geography (Portugal is an Atlantic country and Turkey a Mediterranean and Middle Eastern one) but, despite NATO, for their little political or economic interaction. To enquire into this subject, a neorealist approach and a qualitative methodology were chosen. The concept and theory of small states and group thinking are also part of the analytical framework. Thus, an analysis of foreign policy and diplomatic documents, both of the Portuguese State and the Turkish State, were made, as well as public declarations of their rulers. Additionally, a review of the scarce literature about the subject was carried out. The analysis focused mainly in the last twenty years, when Turkey became candidate for accession to the European Union and negotiations were opened.

本文的主要目的是寻找葡萄牙国家几乎热情支持土耳其加入欧盟的答案。葡萄牙的外交立场很有趣，因为这两个国家在历史上彼此并不熟悉——不仅因为它们的地理位置（葡萄牙是一个大西洋国家，土耳其是一个地中海和中东国家），而且，尽管北约，它们很少有政治或经济互动。为了探究这个主题，我们选择了新现实主义方法和定性方法。小国和群体思维的概念和理论也是分析框架的一部分。因此，对葡萄牙国和土耳其国的外交政策和外交文件以及其统治者的公开声明进行了分析。此外，对有关该主题的稀缺文献进行了审查。分析主要集中在过去二十年，当时土耳其成为加入欧盟的候选国并开始谈判。
