This paper presents activities of The Council of Europe and its bodies – Parliamentary Assembly, Committee of Ministers and Commissioner for Human Rights, as well as activities of European Court of Human Rights as a supervisory body, in promoting the rights and non-discrimination of LGBTI persons. An important role is also played by European Commission against Racism and Intolerance (ECRI), an independent body of The Council of Europe, established in response to the growing racial and ethnic diversity of the European continent. One of ECRI's main activities is monitoring and analyzing the situation in member states of The Council of Europe, in regards to racism and intolerance. Based on this data, ECRI develops measures and guidelines to assist member states in preventing and combating intolerance and discrimination. The aim of this paper is to present ECRI General Policy Recommendation No. 17 on preventing and combating intolerance and discrimination against LGBTI persons. ECRI acknowledges the relatively rapid development of LGBTI rights in the member states but also notices that many challenges in realizing these rights remain. These challenges are multifaceted and cover many aspects of LGBTI persons' lives. This paper focuses on areas of inclusive education (or lack thereof), rise of anti-gender movements and hate speech, as well as the absence of legal accountability for perpetrators of hate speech and violence against LGBTI persons. These areas were selected for detailed analysis as ECRI notes that Croatia still has a long way to go in advancing and improving LGBTI rights in these specific domains. Additionally, the paper presents ECRI's report on Croatia from the fifth monitoring cycle of member states, concerning the rights and status of LGBTI persons.
