End-of-life care is an increasingly relevant topic due to advances in biomedical research and the establishment of new disciplines in evidence-based medicine and bioethics. Euthanasia and assisted suicide are two terms widely discussed in medicine, which cause displeasure on many occasions and cause relief on others. The evolution of these terms and the events associated with their study have allowed the evaluation of cases that have established useful definitions for the legal regulation of palliative care and public policies in the different health systems. However, there are still many aspects to be elucidated and defined. Based on the above, this review aimed to compile relevant historical aspects on the evolution of euthanasia and assisted suicide, which will allow understanding the use and research of these terms.
