The 22nd Annual Conference of the European Society of International Law (ESIL) will be hosted by the Universidade Católica Portuguesa in Lisbon from 9-11 September 2027. The general theme is “International Law and Future(s)”: what future lies ahead for international law, and what international law do we want for the future? All those engaged with international law, including researchers, practitioners, policymakers and other professionals, are invited to submit proposals.
Against a backdrop of profound geopolitical change, mounting challenges to multilateralism, climate and environmental threats, rapid technological advances and artificial intelligence, shifting economic power and growing polarization, the conference invites the international law community to look ahead. The call points to four developments:
The conference will convene twelve agorae, thematically grouped in three clusters. Authors choose one agora only.
Cluster 1, The Future of “Rules”:
Cluster 2, The Future of “Institutions”:
Cluster 3, The Future of “Humanity”:
Proposals are welcome in French or English. Only one abstract per author will be considered. Joint submissions are possible, but a reduced registration fee applies to only one of the selected speakers. Scholars who have not spoken at previous ESIL events are particularly encouraged to apply; submissions from those who were selected or invited speakers at the most recent Annual Conference might be regarded as ineligible.
The programme committee, made up of the agora Chair and representatives of the ESIL Board and the host institution, assesses abstracts on:
Proposals must be submitted online via the conference website www.esil2027.com. The website has an online tool used for the selection process and for all communication between the organizers and applicants. The following is required:
ESIL Interest Groups may submit proposals for agorae, through their conveners via the conference website, by 31 January 2027. A proposal includes:
Selected speakers should submit a first draft of their work (approx. 3,000 words including footnotes) before the conference. The draft is shared with the chair and the other agora speakers to create interaction during the session. The programme committee screens the quality of the drafts and may request amendments.
All selected speakers must register for the conference and are eligible for a reduced registration fee. Early registration after acceptance of the paper also results in a lower early bird fee. The call does not give fee amounts.
A limited number of travel grants and carers' grants are available to ESIL members. To be eligible for a grant, ESIL membership is required by the abstract deadline of 31 January 2027, and the deadline for requesting a grant is 15 June 2027. Application details are on the ESIL website. Selected speakers are expected to bear the costs of their own travel and accommodation; the grants offer partial support to speakers who have exhausted other potential sources of funding.
All participants, including speakers and chairs, at ESIL Interest Group workshops must register for the Annual Conference. There is an option to register for the Interest Group workshops only.
The Prize will be awarded again in Lisbon for the best paper submitted to the conference or to a pre-conference Interest Group workshop by a scholar at an early stage in their career. Early-career scholars are:
Candidates must be ESIL members when they submit the abstract. Co-authored articles are considered only if all authors meet the eligibility criteria. Selected speakers who wish to be considered must tell the ESIL Secretariat before 30 April. The call does not state the amount of the Prize.
After the conference, ESIL offers the opportunity to publish papers in the ESIL Proceedings. Details on how to submit papers for publication are given to all speakers immediately after the conference. The deadline for optional final papers is 1 November 2028.
