The historical development of ethical standards and institutions of Croatian Medical Association is presented. The first standards were "Medical order and Community" in 1895 and the ethical codex under the name "Main principles of Medical dignity" in 1901 resp. 1921. According to the new Association's Statute in 1990 the first "Committee on Human Rights and Medical Ethics" was founded. Since 1995 the Committee operates as a common "Committee on Medical Ethics and Deontology" of Croatian Medical Association and of Croatian Medical Chamber. In short the activities of committees in both periods, 1991-1995 and 1995-1999 are presented, including the establishing of a new "Codex of Medical Ethics". Since 1999 the Croatian Medical Chamber divorced the cooperation with Croatian Medical Association and founded his own Committee. The Croatian Medical Association is now without ethical committee. The establishment of a new, common Committee of the Medical Association, Medical Chamber and Universities is suggested.
