The **European Leadership Network (ELN)** is an independent, non-partisan pan-European think tank focused on enhancing security across Europe through cooperative dialogue, research, and policy advocacy[1][2][9]. Founded in 2011 as part of the Nuclear Security Project, the ELN initially concentrated on nuclear disarmament inspired by President Obama’s 2009 Prague speech but soon expanded its remit to broader foreign, defense, and security challenges affecting the continent[1][2]. Headquartered in London, the ELN unites over 450 current, former, and emerging European leaders from political, military, business, and diplomatic backgrounds, creating a unique network that leverages high-level expertise and cross-border cooperation to address existential threats to European security[1][9]. This network-driven approach allows the ELN to influence security policy effectively through its rigorous research publications, strategic events, and media engagement[1]. **Key achievements** include receiving recognition such as the 2015 Nunn-Lugar Award for Promoting Nuclear Security, awarded to its chair, Lord Des Browne, and former Russian Foreign Minister Igor Ivanov, reflecting its impact on nuclear security dialogue[2]. The ELN has also secured philanthropic support, such as a two-year funding grant from the Carnegie Corporation in 2015, which underpinned its work on complex security issues[2]. In recent years, the ELN has tackled critical risks like the erosion of European cohesion, dangers of unintended conflict, challenges posed by emerging military technologies, and the decline of arms control dialogue[1]. Despite its constructive role, in 2025, the ELN was declared an undesirable organization by Russia, underscoring its contentious position amid geopolitical tensions[2]. Overall, the ELN stands out as a **highly influential European security network and think tank**, dedicated to pragmatic, multilateral solutions aimed at preserving peace and stability in an increasingly complex geopolitical landscape[1][2][9].
