ISD's role

The Institute for Strategic Dialogue (ISD) and ISD Germany will coordinate the coalition to provide space for the participating stakeholders to exchange ideas. Additionally, the think- and do-tank will contribute its innovative research on the threat landscape of online antisemitism. This will create space for the coalition to discuss and develop measures to respond to current developments as they occur.

About CCOA

Antisemitism continues to threaten Jewish life, culture and safety with attacks at record high levels in many countries. Between 2002 and 2021, violent antisemitic incidents in Germany alone had more than doubled. Research suggests that this surge in offline attacks is closely linked to antisemitic narratives that proliferate online with the true scale and nature of this threat often underestimated. Commissioned by the European Commission, one ISD study found an alarming seven-fold and 13-fold increase of antisemitic content across French and German Twitter, Facebook and Telegram, respectively when comparing the first two months of 2020 and 2021. This development appears to have been caused by the Covid-19 pandemic.

Hindered by a lack of platform access, data on this issue can be fragmented and efforts to provide an assessment of the antisemitic threat landscape can be further compounded by a lack of funding in country contexts where the antisemitic threat may be more explicit.

The Coalition to Counter Online Antisemitism (CCOA) was created to get ahead of the rising tide and contribute to a consistent and strong European answer to online antisemitism. To do this, we bring together a range of curate stakeholders combating antisemitism, including CSOs, cities, businesses, practitioners and citizen initiatives, to create new partnerships to counter online antisemitism at scale, We want to amplify existing best practice and build bridges between research, educational measures and policy changes. The pilot phase of this project will focus on five countries: Germany, France, Italy, Poland and Sweden.

The CCOA is an independent pilot project, funded by through 2025.

Call for Papers

The CCOA is seeking submissions for a research compendium on online Holocaust denial and distortion. ‘Combatting Online Holocaust Denial: A Short Compendium’ (interim title), will be published in January 2024 in advance of Holocaust Memorial Day, based off this year’s theme, ‘Fragility of Freedom’. To showcase the expertise in the coalition and the breadth of challenges faced, it will feature 6 contributions from CCOA members across the five countries and three working groups; research, policy and education. We are interested to hear from researchers, policymakers, and civil society organisations with perspectives on the contemporary challenges presented by online Holocaust denial.

Abstracts should be 150-200 words, outlining the key issues the article will aim to address, and the methodologies used. Final papers will be expected to total approx. 1500 words (excluding footnotes). All submissions should be in English and will be reviewed in an editorial process. Successful submissions will be remunerated 400€.

Please send abstracts along with name and affiliation to [email protected] by Friday 3 November 2023.


International CCOA kick-off event

On the 26th of September the Coalition to Counter Online Antisemitism officially launched at a digital event bringing together experts, researchers, and stakeholders committed to tackling online antisemitism. Attended by the EU Commission, representatives of the media and ISD, we are excited to introduce the CCOA’s long-term objectives, the collaborative working groups, and the affiliated members who make up the CCOA project.

How does CCOA work?

Antisemitism needs to be addressed through a whole-of-society approach, bringing together different experts and stakeholders from various fields and industries and across different geographies.  

The exchange of best practices and ideas within the coalition will be facilitated by three working groups in the areas of research, education and policy with results being shared across the coalition. Research data will inform the development of educational material as well as the design of a joint policy roadmap. A final report will outline CCOA’s key findings including:  research data, recommendations to policymakers and an overview of effective educational interventions.

How does CCOA understand antisemitism?

Nowadays, antisemitism may appear in many different shapes and sizes. It has become increasingly mainstream across all parts of society, and often polarises communities, undermines human rights and affects democratic processes.  

There is no one-size-fits-all definition of antisemitism that suits every context. Several organisations use different definitions, depending on their experience and understanding of the term and the context in which it is used. It is not the role of CCOA to decide which definition is “the best” or should be used by other organisations globally. The work of the CCOA centres around the perspectives of those affected.  

In accordance with ISD research, policy and intervention programs, and for the purpose of assessing different manifestations of antisemitism, the CCOA is using the non-legally binding working definition of the International Holocaust Remembrance Alliance (IHRA). The IHRA defines antisemitism as “a certain perception of Jews, which may be expressed as hatred towards Jews. Rhetorical and physical manifestations of antisemitism are directed towards Jewish or non-Jewish individuals and/or their property, towards Jewish community institutions and religious facilities.” In addition to this general definition, IHRA has provided a list of 11 non-exhaustive examples of contemporary antisemitism. 

The European Commission together with the IHRA published several resources that explain how to use the IHRA definition:  


CCOA aims at a whole-of-society approach. We invite organisations working on antisemitism, journalists, lawyers, researchers, football clubs and more who may have an interest in the work of the CCOA to join us.

The CCOA provides a space for organisations and practitioners to build capacities and an intersectional understanding of online antisemitism, aiming at equipping members with the tools and knowledge needed to face an increasingly complex online threat landscape.

The working groups will come together once a month to exchange new findings in their respective fields. These meetings will take one or two hours and are not mandatory. Working outputs are continuously shared via internal channels so you can stay up to date even if your schedule does not allow you to take part in meetings.

Members will be connected to change-makers and experts across sectors on a Pan-European level. Communication through internal channels will foster the connection with experts and fellow coalition members. The coalition will benefit the exchange of knowledge, research and best practices. 

ISD has long-standing dedicated digital policy expertise across online harms and the wider digital landscape, research expertise and digital analysis tools to provide unique insights on online antisemitism and the overall threat landscape. ISD also has extensive experience in developing intervention programs shaped by their evidence-based research and analysis.
